Here's Why You Should Always Tip Your Delivery Driver With Cash

In our microchip- and app-happy society, we’ve all but abandoned paying for things in cold, hard cash. And while that’s almost definitely more efficient for you, it could be costing your delivery driver their tip, Lifehacker reports.

Some food delivery services guarantee a minimum payment for their drivers, which seems like a good thing on the surface. Basically, the company will pay the driver the agreed-upon base payment, even if it’s a slow shift and they don’t actually reach that amount in delivery charges. But it also means that everything they earn, including tip, is going toward that base payment. In other words, your tip is saving the company from having to pay more of the base payment.

The best way to ensure that your tip goes into your driver’s pocket is to give them a tip that they can literally put in their pocket—namely, cash. If you don’t have cash around or like to keep your finances digital for credit card rewards or tracking purposes, you should choose a delivery service that promises to pay their employees the full amount of whatever they earn, including tip.

Take a look at Lifehacker’s handy breakdown below to find out which delivery services you can trust with your tips, and read the policy details for each service here.

Keep in mind that this is only for companies whose whole business is based on being the go-between for you and your favorite restaurant. If you’re ordering directly from a restaurant, make sure to ask about its own delivery rules, or just tip in cash to be safe.

Why You Shouldn’t 'Heat Up' Your Car's Engine In Cold Weather

When the inside of your car is no warmer than the frozen tundra outside, it’s easy to believe you need to let your engine “heat up” for a minute or two by idling in your driveway before driving away. The old adage goes that giving your engine time to reach its normal operating temperature is easier on your car than hitting the gas as soon as you turn the ignition on. One 2009 study showed that, on average, Americans believed a car's engine should be left to idle for nearly four minutes in subfreezing temperatures—but it turns out this behavior is not only bad for your wallet and the environment, but your car as well.

In 2016, Business Insider spoke with former drag racer Stephen Ciatti to get to the bottom of this widespread myth. Ciatti has a PhD in mechanical engineering from the University of Wisconsin-Madison and has worked on combustion engines for nearly 30 years, so he knows a thing or two about how to best treat your car. And he says that idling your machine in the cold only leads to a shorter lifespan for your engine.

In older car models that relied on carburetors to run, frigid weather did pose a threat to engine performance. Gasoline is less likely to evaporate in colder temperatures, which would have led to carburetors failing to get the right mixture of air and fuel into the engine. This sometimes caused cars to stall out, and that's likely what led to the practice of heating up our vehicles in our driveways in the winter. But if you’re driving a car that was made in the past few decades, this is no longer something to stress over. Beginning in the 1980s, car companies began replacing carburetors with electronic fuel injection, which uses sensors to calculate the correct mixture of air and fuel to supply your engine with.

When temperatures dip below freezing, your engine is already aware of this and adjusts by introducing more gasoline into the fuel mix. By letting your car idle, you’re subjecting your engine to more gasoline-rich fuel than necessary, and this ends up stripping oil from your engine’s vital components.

"Gasoline is an outstanding solvent and it can actually wash oil off the [combustion chamber's] walls if you run it in those cold idle conditions for an extended period of time," Ciatti told Business Insider. He said this washing action can gradually "have a detrimental effect on the lubrication and life of things like piston rings and cylinder liners." So in the end, what you intend as gentle behavior toward your car’s engine could turn out to be the opposite.

Once your engine reaches a temperature of around 40 degrees it switches back to its regular fuel mixture, but idling doesn’t help it hit that point any faster. According to Ciatti, the fastest way to heat up an engine is to actually drive. But don’t take that as an excuse to go gunning down the driveway: Your engine will take between five and 15 minutes to reach a normal temperature from the moment you hit the gas. Until then, go easy on the pedal to avoid putting additional stress on your engine.

The Reason Elections Are Held on Tuesdays

Ever wonder why Americans always vote in federal elections on Tuesdays? There are a few reasons—including a little something to do with the horse and buggy.

Between 1788 and 1845, states decided their own voting dates. In 2012, then-Historian of the Senate Don Ritchie told NPR that strategy resulted in chaos, a "crazy quilt of elections" held all across the country at different times to pick the electors—the white, male property owners who would cast their votes for president on the first Wednesday of December. In 1792, a law was passed mandating that state elections be held within a 34-day period before that day, so most elections took place in November. (Society was mostly agrarian; in November, the harvest was finished but winter hadn’t yet hit, making it the perfect time to vote.)

The glacial pace of presidential elections wasn't a huge issue in the late 18th and early 19th centuries—communication was slow, so results took weeks to announce anyway—but with the advent of the railroad and telegraph, Congress decided it was time to standardize a date. Monday was out, because it would require people to travel to the polls by buggy on the Sunday Sabbath. Wednesday was also not an option, because it was market day, and farmers wouldn’t be able to make it to the polls. So it was decided that Tuesday would be the day that Americans would vote in elections, and in 1845, Congress passed a law that presidential elections would be held on the Tuesday after the first Monday in November.
