There's a lady who has shaken my faith in my ability to read people. She's called the "Warm Chip Lady. "
Several times a week the warm chip lady and her pre-teen daughter come into the restaurant where I work and request their favorite server. If he's not there they have a back-up list. When they've been seated, she requests "just a warm snack. Just a little snackety today," all the while scrunching up her nose like some marsupial mating call. She requests warm chips and a Diet Coke and asks for refill after refill and never orders a real meal. She leaves a fifty cent tip.
During the time the server was helping her, he could have been helping someone else who would have left a real tip. The thing that is so terrible to me is that she thinks the servers are delighted to be requested. And sure, that's nice, but no waiter cares whether you like him if you don't tip. So the question is one of whether I do this to people, whether, in fact, we all do it to each other all the time. Do I think I'm being nice by dropping in on friends, when really all they want is some quiet time? Et cetera.
