I would much rather have some fast food worker tell me they don't want me there, than have them "add" something to my order. Although I am beginning to suspect that a (I was going to say older, but she's about the same age as me) waitress in a restaurant I frequent doesn't like me very much. Probably because the amount I tip is based on the service or I may have dated her in the 80's. If you work where your pay is low and tips are your primary income, don't interact with the patrons with a scowl on your face and a bad attitude.
