It's not a Friday's I usually go to so I prob won't be going there anytime soon. I just don't get how she thought it would be cool to take the change as her tip. I never said it was all set. I work for tips, too, as a bartender and even if people say it's all set, I still put the change on the counter and let them leave it. I always feel like I'll mistake them saying it's all set and they'll look at me like I'm dumb if I don't give them change.
