I always try to over tip a breakfast waitress and feel guilty when I can't
Why do you like to over tip a breakfast waitress?
I just like to do it because it seems like they deserve it.
It's good to give servers big tips because their income depends on it. I think people should tip well for good service if they can afford it.
I feel bad for people with part time...
It's nice of you to give big tips, but it's not required. If you find that you don't have the funds sometimes, a regular tip is okay, too and you shouldn't feel bad.
