Fancy-shmancy restaurants of the type that I avoid.
20 percent or better here-- with the very rare exception, demonstrated the other month when I had to wait half an hour for some teenager to decide to come over to the table so I could freakin' order coffee, let alone anything else. That kid is lucky I left her anything at all.
The place was not that busy, btw.
The tip is automatically included for large tables, so it was on the ticket our head guy received and paid. The waitress had the nerve to act upset that he didn't tip her, and demanded cash on the spot. Dumbest thing I ever saw.
