Quote from Carla in Home Malone
Kelly: Carla, I just waited on a man at table 5 and he left too much money on the table. Should we go find him? Carla: No, uh, you see, this is what we call a tip. It's a little monetary gift for the head waitress. Kelly: Here you go. Boy, do I feel dumb. Carla: Oh, no, you're just new.
