I went out to dinner with a friend of mine. I am overweight, she's underweight bordering on skeletal at times. We decided to share a large dish of food rather than order our own food and she proceeded to eat 90% of it. But she's also painfully shy, so couldn't ask the waiter for more food. So I called the waiter over and told her what we would like to order next. Her jaw DROPPED, stared directly at me and said in a disgusted tone of voice, "YOU want MORE food?!?!?!?"
And yes, I did complain, and no, I didn't tip her.
