Intoxicated people are idiots
Some people who go to a bar or restaurant need a server. Others need a babysitter, because they act like children. And being a babysitter sucks, unless the kids have gone to bed and there's lots of good stuff in the fridge.
The drama is real
Close spaces, "interoffice" relationships, long hours, relying on other people. We'll spell it out for you: D-R-A-M-A. And the casual nature of a restaurant or bar amplifies the type of friction that's just white noise in a real office.
Management nearly always sucks
Corporate, management, The Man, whatever you want to call them -- they're usually awful. No matter how great the workplace, there's bound to be a thorn in your side coming from up high.
