Just as a heads up - if you choose not to tip then there's a good chance your waitress will literally lose money by serving your table.

Some places will expect the wait staff to 'tip out' to the back of house based on the total bill, not what she's tipped. So of you stuff her on a $100 bill, she may end up paying $10 out-of-pocket to cover your lack.

Its bullshit, I know. Which is why I often avoid full-service establishments.

Bullshit? That should be illegal, but I appreciate the information.
