One of my co-workers told me about this earlier......and he also told me about a guy licking the shells of a bunch of tacos, and a chick spitting in nachos (both at Taco Bell of course)
I myself saw a guy on some 'caught on camera' show swirling his meat around in the drinks everybody ordered.
:x I need to become a cook/chef, or do nothing but fire up the grill at home
Actually pretty mild in the world of food service workers messing with people's food, even if you just compared it to what people have admitted to doing themselves.
