As a server/bartender for nearly 4 years now, I have witnessed other employees on every level do things to customers' food or drink at all 7 restaurants that I have worked at. I say nothing to stop them nor do I report them.
From cooks bringing urine and semen in a bottle to put in food, spraying Windex in pasta, busboys spitting in or wiping shit off the bottom of their shoe for food that was to be wrapped up to-go, servers licking fingers or reaching down for some ballsweat and sticking them in drinks before serving them, bartenders that keep extra bottles of liquor that are contaminated with chemical or body fluids so you can watch them pour a perfectly acceptable drink and you'd never know it's been fucked with (piss off your barkeep and you're fucked), even managers dropping food on the floor on purpose and serving it.
My only defense, first off I have never personally participated in this practice, second is that every time this has happened, it has happened to a complete asshole customer. Any other field and the person would have been thrown out of the store/business already.
Please people, do not fuck with the food industry. And if you're going to look down on these people or give them any attitude, do not ask them to box up your food for you. Never let your food leave your sight.
Not saying anything is just as bad as participating. Also, no one ever deserves that. I don't care how much of an asshole they are. Don't you realize you could fucking kill someone doing that?
You might feel that they don't deserve it, but that is proof that you have probably never been treated the way some people treat the wait staff.
You're like the Joe Paterno of the food industry... Knowing its happening and not doing anything about it
If you're going to use that analogy, then you're claiming Joe Paterno didn't report it because he wished that he could have been the one raping a minor but just didn't have the balls to do it himself.
I wish/want to do that to customers that are self-involved assholes. I just can't bring myself to actually go through with it. So I live vicariously through other less scrupulous people.
