I have to disagree with matthewcmill.

You are paid to provide a service. You charge what the traffic will bear. I read your post where you claim that some of the hunts you set up cost $30,000 and you get get 8%. That works out to $2400. Now tell me again why I should tip you.

I have walked out of one or two restaurants in my life without being at all generous. My older brother once told me "Never leave the restaurant without leaving a least a dime for lousy service. They need to know that they got what their service was worth."
