Fast food employees, what is going on with you?! Your job is simple: You make French fries, hand out hamburgers and, if you're lucky, you get to wear that drive-thru headset from time to time. Wearing that headset seems really awesome.
So news flash: Stop doing gross stuff to the food! And if you are physically incapable of not licking stuff and eating food and sticking who knows what where, then first of all, c'mon, bro. C'mon. And second, don't take pictures of it!
If you were to sum up the latest incident, Clue-style, it would be: It was that dude in the Wendy's with the Frosty machine (not even chocolate Frosty, which would be slightly more excusable, but the vanilla kind. Which...why?!)
