When we were in the DFW area for Young Epic's conference tournament, we ate breakfast several mornings in the Denny's next to the hotel. A waitress told us one morning that for three different meals, totaling $600+, a coach for one of the tournament teams (not our coach) left no gratuity. The waitress of record (whose ID goes into the computer system) has to pay taxes on 15% of the bill, even if no gratuity is left.
By the time we heard this, that team was out of the tournament. I emailed the president of the university, and within hours had a response from the coach. He thought the gratuity was figured in the total bill, and he is sending $100 to the Denny's.
I wonder why the manager of the Denny's, the second or third time the team came in to eat, did not at least ask the coach if he was displeased with the service and as a result did not leave a tip?
