Late Night Waitress

I went to IHOP at 11pm yesterday with a couple of friends. Now, I realize that the busier shifts are assigned to the best wait staff, and so I expect lazy service during late night hours at a restaurant. But I was not prepared for this waitress. The service was lousy, the wait for food was ridiculous, my food was a little overcooked, but I was there for the company of friends, not the food. At the end of the meal, she brings the bill and asks if she can clear a few plates out of the way. We all lean away from the table, pulling arms back, so that she has room to maneuver. She stacks several plates and then instructs me to hand her that drinking straw wrapper, that napkin, that bowl, etc. Instinctively, I began to do as I was told. As I’m gathering up the requested items, I suddenly realize that I she has assumed a relaxed posture, resting her hip against the booth while I do her work! I said very calmly, “How much tip should a person leave, if they have to buss their own table?
