I can be a jerk at times, but never to wait staff. Once, when I took a client in a restaurant, the client's wife was being drunk and irate and started a scene with the waiter. I calmly pulled the waiter to the side, told him that she had a bit too much to drink and slipped him a 20 and told him I'd take care of him after we got out of there. I told her that I talked to him and set him straight. He came back and apologized to her, got her what she wanted and my client was happy because his wife is a huge bish and he is a mangina.
