Since opening its very first store in Germany in 1961 and then coming to America in 1976, discount grocery chain Aldi has grown to over 1900 stores in 36 states. Using inventive cost-cutting measures—customers are responsible for returning their own carts and the store charges for bags unless you bring your own—the brand has become synonymous with quality at an affordable price.

Tasked with overseeing the long hours of daily operations are the company’s 25,000-plus store employees, who are typically part of a small team of 20 or fewer people per location. Aldi workers are expected to be proficient in everything from unloading pallets and stocking shelves to checking out customers at a speed that meets or exceeds standards—employees are even timed on how fast a customer pulls out their credit card.

To find out more about this challenging line of work, Mental Floss reached out to several current and former Aldi employees. Here’s what they had to say about memorizing barcode numbers, how many miles they walk during a typical shift, and why sitting down at the register is actually more efficient than standing.

1. Working at Aldi means walking. A lot.

At Aldi, employees aren’t given set roles when it comes to unloading, stocking, cleaning, or working the register. Everyone is expected to be able to do everything, which means a lot of physical effort. “Our job is considered physically demanding, because Aldi has very few employees running per shift, meaning there are more expectations placed on each of us,” Jonah, an Aldi employee in Pennsylvania, tells Mental Floss. “If you aren't ringing, you are expected to be cleaning, stocking, re-stocking, or organizing the shelves. There is no ‘down time.’”

That suits many employees just fine. “I don’t like to sit around and do nothing, and this job is the complete opposite,” Kyle, an Aldi employee in Virginia, tells Mental Floss. “I actually wear a Fitbit when I work, because I have been curious about how many steps I take. I average about 127,000 steps every [five-day] work week. I’d say an estimate is 25,400 steps a shift.”

2. Aldi employees sit down at the register for a very good reason.

Employees can sit on stools while ringing guests up at a register, but getting a little rest isn't the sole reason for the seat. “While [resting] is true, Aldi says that cashiers sit at the register because, according to their testing, it allows us to ring up items faster,” Jonah says.

3. Aldi employees are monitored for their ringing speed.

Part of the reason Aldi can get away with as few as three to five employees in a store at any one time is because customers can be processed quickly. Aldi typically sets performance standards for employees at the checkout, who might be expected to process as many as 1200 items per hour. “We are given reports at the end of each day for our ringing statistics,” Jonah says.

And that’s not the only performance metric used to evaluate workers. “Ringing is the only part where we get an actual report, but managers will tell us that we are expected to knock out two pallets per hour, or one pallet every half hour," Jonah says.

4. Aldi employees “train” customers to move quickly.

Part of an employee’s register performance review depends on how quickly they can get a customer away from the register and toward an area where they bag their own groceries. To do this, employees encourage customers to have their payment method ready and inserted into the card reader before their items are done being scanned. “Aldi is all about efficiency, and encouraging our customers to ‘pre-insert’ their card while we are ringing allows the payment process to be near instant, rather than having our customers wait for us to finish ringing and then pull out their card and insert it,” Jonah says.

5. Aldi employees need Tetris-type skills to load carts.

When an employee rings up a customer, items are loaded from the cart to the conveyor belt and then back into the cart. Because heavier items need to be placed first, employees need to be strategic when placing products. “[We put] light items like eggs, bread, chips, etc. at the top of the cart and everything else on the bottom,” Sara, an Aldi employee in Indiana, tells Mental Floss. “However, it really just depends on the order that customers put their items on the belt.” (They prefer you put heavy items like bottled water first.)

For maximum efficiency, Jonah prefers customers take products out of their display boxes and avoid trying to bag their groceries while cashiers are still ringing them out. “It slows us down and causes a longer wait for everyone,” Jonah says.

6. Aldi employees memorize barcode numbers.

Ringing speed is so crucial to Aldi’s success—and an employee’s job performance—that many workers memorize barcode numbers to keep the line moving. “Items like milk and water have codes that we memorize,” Sara says. “For example, someone could be buying six gallons of milk, and instead of having the customer put all of them on the belt for us to scan one by one, we tell them to leave them in their cart and we key in the codes, making the checkout process faster.”

7. Aldi employees may or may not give you a quarter if you forget one.

Because it would take time and money to collect shopping carts, Aldi has a system where customers insert a quarter to unlock a cart from the collection area. When they return it, they get the quarter back. But not all customers remember to bring a quarter, and first-time shoppers might not even know they need one. And if they ask an Aldi employee to borrow one, they may or may not get it.

“I try not to give them a quarter because the quarters we give come out of our own registers,” Kyle says. “So if we don't get them back, we end up losing money out of our own drawer. If it's a first-time shopper, I gladly give them a quarter and explain to them why we have this system in place, and pretty much every person is very understanding on why we do it.”

If you’re short a quarter, don’t try shoving anything else in the slot. “People will try to use foreign currency that are the same size as quarters,” Kyle says. “Doesn't hurt us; it's just annoying to deal with.”

8. Aldi has a store phone, but customers shouldn’t bother calling.

Aldi keeps the phone numbers for individual stores unlisted, preferring that employees deal with customers already in the store. Limits are placed on when the phone can be used. “We do technically have a store phone, but this phone is strictly used for receiving calls from the warehouse, global help desk, and to our security company we use,” Kyle says.

9. Aldi’s return policy is something employees can find a little too generous.

Aldi has a unique return policy for items purchased in their stores. Under their Twice as Nice Guarantee, customers can return a product and not only get a replacement item but a refund, as well. “Our Twice as Nice Guarantee is a very good system; I'd say one of the best in grocery,” Kyle says. “That doesn't mean it's perfect, though. I have seen people abuse this system. It's happened in my own store numerous times.”

Kyle declines to explain how it’s abused, though anecdotal reports are that perfectly good items are sometimes brought back to exchange for the benefit of a new item plus the refund. Serial returners are sometimes flagged and told to ease up. (The policy is currently suspended due to the coronavirus pandemic but is expected to return in the future.)

10. Aldi employees are required to wear steel-toed boots.

Check out the footwear of an Aldi employee and you’ll notice they have on steel-toed boots normally seen on construction sites or warehouse jobs. That’s because workers are expected to unload the massive inventory pallets that arrive regularly. “All associates are required to wear steel-toed boots because of the equipment we use on the job,” Kyle says. “We use pallet jacks and it is just a safety precaution.” (Aldi does reimburse workers for the boots.)

11. Aldi employees appreciate you taking the survey.

The customer surveys that appear on Aldi receipts might go ignored by many, but they serve a real purpose. Employees are expected to meet a store quota of completed surveys, and customers can actually influence the selection inside the store. “We encourage customers to fill them out if they want a certain item brought in since the surveys go straight to corporate,” Sara says.

Regardless of how they offer their input, customers can often get what they want. “One thing that may surprise people is that you have a very strong voice on what items we should carry in our stores,” Kyle says. “A prime example of this is the [L’Oven Fresh] Zero Net Carb Bread. It was an Aldi Finds [a limited-time item] and people wanted this item to be a normal item so badly, and the company listened.”

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

10 Secrets of Epidemiologists

Epidemiologists are fans of charts.

Unless you know an epidemiologist or are one yourself, those “disease detectives” might not have occupied a very large portion of your brain. Last year, that is. Now, with the coronavirus pandemic at the top of mind—and at the top of so many headlines—there’s a good chance you’re at least aware that epidemiologists study diseases.

To be more specific, the Centers for Disease Control and Prevention (CDC) defines epidemiology as “the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems.” So what exactly does this mean? Mental Floss spoke with a few epidemiologists to shed light on what they do, how they do it, and which germ-friendly foods they avoid at the buffet.

1. People often mistake epidemiologists for skin doctors.

Since the word epidemiologist sounds like it might have something to do with epidermis (the outer layer of skin), people often think epidemiology is some offshoot of dermatology. At least, until the coronavirus pandemic.

“Prior to that, no one knew what I did. Everyone was like ‘Oh you’re an epidemiologist—do you work with skin?’” Sarah Perramant, an epidemiologist at the Passaic County Department of Health Services in New Jersey, tells Mental Floss. “I would be rich if I had a dollar for every time I got asked if I work with dermatologists.”

2. Epidemiologists don’t discover a new disease every day.

Though some epidemiologists do look for unknown diseases—certain zoonotic epidemiologists, for example, surveil wildlife for animal pathogens that might jump to humans—most are dealing with diseases that we’re already familiar with. So what do they do every day? It varies … a lot.

Epidemiologists who work at academic or research institutions undertake research projects that help determine how a disease spreads, which behaviors put you at risk for it, and other unknowns about anything from common colds to cancer. But it’s not just about devising experiments and studying patient data.

“I like to tell my friends and family that my job is about four different jobs in one,” Dr. Lauren McCullough, an assistant professor in the department of epidemiology at Emory University’s Rollins School of Public Health, tells Mental Floss.

Writing, she says, is “the most important part.” It includes requesting grants, devising lectures and assignments, grading her students’ work, writing about her research, and more. She also sits on admissions committees, reviews other epidemiologists’ studies, and oversees the many people—project managers, data analysts, technicians, trainees, etc.—working on her own research projects.

Those who work in the public health sphere are often monitoring local outbreaks of diseases like the flu, Lyme disease, salmonellosis, measles, and more. If you test positive for a nationally notifiable disease (any of about 120 diseases that could cause a public health issue), the CDC or your state health department sends your electronic lab report to the epidemiologist in your area, who’s responsible for contacting you, finding out how you got sick, and telling local officials what steps to take in order to prevent it from causing an outbreak.

3. Epidemiologists have to make some uncomfortable phone calls.

Epidemiologists sometimes have to ask pretty personal questions about drug use and sexual activity when trying to figure out how someone got infected, and not everyone is happy to answer them. “I’ve gotten hung up on many a time,” Dr. Krys Johnson, an assistant professor in Temple University’s department of epidemiology and biostatistics, tells Mental Floss.

Some simply aren’t willing to accept that they might have been exposed to a disease without knowing it. After several employees at a certain company tested positive for COVID-19, for example, Perramant started calling the rest of the workers to tell them to go into quarantine; this way, she could prevent sick people who weren't yet showing symptoms from spreading the disease without knowing it. But not everybody was open to her advice. “They would just swear up and down, ‘I haven’t been in touch with anybody who’s positive, please don’t call me again,’” Perramant says.

But there are plenty of cooperative people, too, especially victims of foodborne or diarrheal illnesses. “They really want to know where they got sick because they’re so miserable that they never, ever want to deal with that again,” Johnson explains. Parents of sick kids are also generally forthcoming, since they want to keep their kids healthy in the future. And then there are those who don’t have any problem spilling their secrets to a stranger.

“There was one woman who was very memorable,” Johnson says. “I called her about her Hepatitis C, and she was like, ‘Oh, honey, I did drugs back in the ’80s. That’s where I got my Hepatitis C. I pop positive every time!’”

4. Epidemiologists deal with a lot of rejection.

Public health epidemiologists have to learn to just shrug off all the rude tones and dial tones, and epidemiologists in academic settings need thick skin for different reasons.

“There’s just a lot of rejection,” McCullough says. “‘That idea isn’t good enough; this paper isn’t good enough; you’re not good enough.’ That is just a resounding thing. There’s a high bar for science; there’s a high bar for federal funding; and it takes a lot to cross that bar. So in the academic setting at these top-tier institutions, you really just have to have a thick skin.”

5. Just because epidemiologists' guidelines change doesn't mean they're wrong.

Sometimes, McCullough explains, the story of a disease can change over the course of one study. When you look at the first 100 people in a 10,000-person study, you’ll see one story emerge. By the time you’ve seen 1000 people, that story looks different. And after you’ve seen the data from all 10,000 people, the original story might not be accurate at all.

Usually, epidemiologists can complete the whole study of a disease and draw conclusions without the world clamoring for half-baked answers. But with a brand-new, highly infectious disease like COVID-19, epidemiologists don’t have that luxury. As they’ve learned more about how the pathogens spread, how long they can survive on surfaces, and other factors, they’ve changed their recommendations for safety precautions. Everyone else in the world of epidemiology expected this to happen, but the general public did not.

“If we say something this week that contradicts what we said last week, it’s not that we were wrong,” Johnson says. “It’s that we learned something between those two time points.”

6. Being an epidemiologist would be easier if people kept better track of their behavior.

Often, people omit vital information about how they got exposed to an illness because they just don’t remember all the details. You could easily recall devouring a few slices of the decadent chocolate cake your mom baked for your birthday last Friday, but you might not be able to name every bite of food you ate on a random Thursday three weeks ago.

“People aren’t telling us the whole truth, but it’s not that they’re being intentionally obtuse,” Johnson explains. “With recall bias, unless there’s a reason for us to really remember, we’re not going to remember everything we actually ate.”

This has made it especially difficult to trace an aerosolized disease like COVID-19.

“All my friends going into the Fourth of July were like, ‘Should we have a get-together?’” Perramant says. “And I said, ‘You can have people over, but you better take an attendance list. You better have a little spreadsheet on Google Drive that has every person’s name and their phone number, so that when one person tests positive and gets sick this week, when I call you, you will be able to give me that information like that.’”

7. Epidemiologists have reason to be wary of buffets, cruise ships, mayonnaise, and cubed ham.

Infectious disease epidemiologists may have accepted that germs are a part of life, but they also know where those germs like to congregate.

“I don’t go to buffets, I have never been on a cruise ship and I don’t intend to, I’m super conscientious when I fly,” Johnson says. “And I’m really aware of whenever mayonnaise-based things are put out at family functions. If you’re ever at a potluck and people come down sick, the first thing people say [they ate] is potato salad or egg salad, because mayonnaise can spoil so quickly.”

“[Cubed ham] is one particular microbe’s very favorite thing to multiply on, so if you’re gonna have ham, make it a whole ham,” she says.

8. Teaching people is a really rewarding part of being an epidemiologist.

In addition to actually leading lectures in the classroom, academic epidemiologists also work extremely closely with their students on research projects; McCullough estimates that she’s in contact with hers at least once a day when they’re collaborating on a study.

“To work with someone so closely, and to watch them progress as a scientist and as a person, and then to have to let them go and send them out into the world, I find that very rewarding,” McCullough says of her trainees. “As a scientist in an academic institution, there’s not a whole lot of immediate gratification. Our papers get rejected, our grants don’t get funded, but the trainees are always a source of immediate gratification for me, so I hold them close to my heart.”

Epidemiologists in other spheres have teaching opportunities, too. When a community experiences a disease outbreak, public health epidemiologists like Perramant are responsible for helping the general public understand what they can do to prevent the spread.

“I like to teach kids about infectious disease and infection prevention for what’s relevant to them. We’ve had a couple of large outbreaks at summer camps, and last summer I put together a training for camp counselors,” Perramant says. “That’s always a part of my job that I really love.”

9. Epidemiologists have a unique understanding of racial disparities.

At this point, it's exceptionally clear that COVID-19 is disproportionately affecting people of color in the U.S. They're more likely to be exposed to it, they have less access to testing, and the preexisting conditions that place them at a higher risk can be the result of systemic racism. When these trends started to become apparent, McCullough got flooded with phone calls asking why. Her answer? This isn’t new. As she’s seen in her work as a breast cancer researcher, Black women are more likely to die of that disease than their white counterparts, and similar health disparities exist across the board.

McCullough explains that the general public is finally realizing what epidemiologists already knew: That poor disease outcomes in minority, low-income, and rural populations aren’t because of anything those people are doing on an individual level. Instead, it’s a result of systemic issues that keep them from leading financially comfortable, healthy lifestyles with access to healthcare and other resources.

“It’s not just COVID—it’s almost every single chronic and infection ailment that’s out there,” McCullough explains. “So this is a real opportunity for people to step back and take an assessment of where we are in terms of our healthcare system, and what we’re doing so that everybody has equitable outcomes. Because people shouldn’t die just because they live in a rural area, or just because they’re poor, or just because they’re Black or Hispanic.”

10. They've had to deal with a lot of “armchair epidemiologists” lately.

Until this year, epidemiologists had to suffer through people mistaking them for dermatologists. Now, during the coronavirus pandemic, people finally know at least a little about their jobs. In fact, people are so confident in their newfound epidemiological knowledge that many are fancying themselves experts on the subject.

“At the beginning of 2020, there were like 500 epidemiologists, and now there are about 5 million. Everybody thinks they’re an epidemiologist,” McCullough says. “There’s a science to it, and it’s a science that requires training. We went to school for a really long time to be doctorally trained epidemiologists.”

It’s not just about advanced degrees, either. Beyond that, you need years of firsthand experience to grasp all the nuances of understanding methods, interpreting data, translating your findings into recommendations for the general public, and so much more. In short, you can’t just decide you’re an epidemiologist.

Perramant has her own analogy for the recent influx of self-proclaimed epidemiologists: “It’s like armchair psychology. Poolside epidemiology now is a thing.”
