This is list of things that piss off a waiter/waitress. Personally what I hated as a waitress was unhappy customers. This list is a made from people who complain a little too much. If you are bitching about a tip you did not get, it probably did not deserve it.
Actually I'll burn it down in my section to let a kid order for themselves or say thank your or anything like that. Otherwise we will end up with a generation of adults who can't speak for themselves and are rude
