It's only common if you're a blatant jerk. I worked fine dining, and dealt with the types who drank bloody mary's (extra extra strong) for breakfast, martinis for lunch, and maybe solid foods for dinner. I've been physically assaulted because someone didn't like how I split the check, even though it was exactly what they asked for. I've been berated because someone didn't understand that the ribeye they ordered is supposed to be a fatty piece of meat. I've had a gun waved in my face because someone didn't get the table by the fireplace. You treat someone like that, and you can expect your food to be fucked with. Dropping items on the floor and placing them back in the plate, eye drops in the water, dish water used for cooking, dirty utensils simply wiped off behind the door and then handed back, etc are all common for the truly vile customer. If you're nice to your server, they will remember and treat you with respect so you should never have anything to worry about.I wonder how common that is...? And what do you mean exactly. Hearing stuff like that makes me not want to eat out.
I hear that. I loved food running and hostessing. Less pressure, more freedom, and good tipout ;DI bussed at a nice restaurant for a year or so. I really enjoyed it. I didn't have to wait tables, which I hated, and got to goof around with the waiters, cooks and, BONUS, bar tenders! Lots of freedom and decent tips.
