I don't want to tip
Why don't you want to tip?
It makes me feel powerful. I'm the customer, she's the waitress.
I guess it all depends on the level of service you got. If she did a good job, you should tip to show your appreciation.
If I use the logic you just said, then don't you think I should tip her?
Yes, I think it's important to tip restaurant staff as their hourly pay depends on tips throughout the day.
