After Popeyes released its new chicken sandwich last week, a heated battle broke out on Twitter over which fast food chain offers the best one. Favorites included Chick-fil-A, Wendy’s, and KFC, but the Publix chicken tender sub was mostly absent from the dialogue. Maybe it’s because Publix is a supermarket rather than a fast food restaurant, or maybe the southern chain is too specific to Florida and its neighboring states to warrant a national ranking.

Either way, the chicken tender sub is a cult culinary classic among Publix customers—there’s even an independently run website devoted to announcing when the subs are on sale (they aren’t right now), and affiliated Facebook and Twitter accounts with tens of thousands of followers. So whom do sub devotees have to thank for inventing the Publix food mashup from heaven? A Facebook user named Dave Charls says, “Me!,” but Publix begs to differ.

The Tampa Bay Times reported that in May of this year, a man named Dave Charls posted a message on the “Are Publix Chicken Tender Subs On Sale?” Facebook page recounting his origin story for the menu item, which allegedly took place in 1997 or 1998. At Charls explains it, he and his co-worker Kevin convinced their friend Philip, a deli worker at the Fleming Island Publix location, to assemble a sub with chicken tenders and ring it up as one item—something that deli workers had refused to do for Dave and Kevin in the past. According to Dave, Philip then convinced his manager to make it a special, publicized it via chalkboard sign, and the idea spread like hot sauce.

“You’re welcome,” Charls said. “It was actually Kevin’s idea and Philip brought it to life.”

Publix, however, told the Tampa Bay Times that its recorded documentation for a chicken tender sub recipe and procedure goes all the way back to 1992 or 1993. Based on that information, Publix spokesperson Brian West confirmed that Charls's heroic account of the origin is more fairytale than fact (though West, unfortunately, doesn’t have an equally thrilling origin story—or any story at all—with which to replace it).

Charls didn’t respond to a request from the Tampa Bay Times for comment, so we may never know how much of his claim is actually true. It’s possible, of course, that Publix’s 1992 (or 1993) chicken tender sub recipe hadn’t gained momentum by the time Kevin’s moment of culinary genius struck in 1997 (or 1998), and the lack of date specificity suggests that neither party knows exactly how it went down. What is incontrovertible, however, is the deliciousness of Publix's beloved sub sandwich.

"I'm just happy to live in the same timeline as this beautiful sandwich," says die-hard Pub Sub fan (and Mental Floss video producer/editor) Justin Dodd. “Copyright claims aside, it's truly a wonderful thing."
