I've been at this for some amount of time, the schools not being exactly on the ball about gate receipts has been an ongoing deal. Most of the time the season tickets are not counted in, it makes a big crowd pay cheap.
I'm not real big on the pay schedule, I do it because I like the game, the exercise keeps me in a half way decent shape, it gets me off the place several nights a week, and it's a bit of payback for some other guy doing it years ago. If you have the time and energy to figure every penny spent on a Friday night, you just might have too much time on your hands.
