You have no idea. The only ones of these, as a food service lifer, that I really identified with was the stiff and the people angling for free shit. The rest is irritating primarily to other customers (valid, just not something somebody who works in restaurants will likely ever experience due to...) and the corporation that owns the joint.

Food service slaves do more for less than almost any other category of work, and we are abused from both ends. It goes most of the way up the chain, too. Management from the district level down is a neverending nightmare of trying to get those above to listen to the plight of those below, who see you as the problem.

I've worked just about every job category. Assistant Manager is the worst, followed by server.

When I started in food service, in the early 80's, it was an honorable and livable profession. There were bad actors and bad customers, but they were the exception. When I got out, finally, a decade ago?

I would not recommend a food service job to my enemies. I'm not that mean.
