skimming?

Note at the bottom of the daily log dated 6-20-08: Water polo does not pay. What should we do? Note 5-23-08 at the bottom: Water polo is not-for-profit group. Apparently this information is accurate. Does this mean that all the other groups pay a cash admission? Like the Doral coach said he paid $2 a swimmer per day? That would amount to a nice chunk of cash every day that is NOT accounted for in the logs. Is it possible that is a part fo the handshake deal between the City Manager and MDAC? Has the handshake agreement EVER been revealed, as to what EXACTLY it entails? Were there any witnesses to the handshake deal? Is it possible that MDAC pays $2 each swimmer every day in cash, or weekly, and THATS why they dont think they owe anymore rent? Could THAT be why Gym gave them such a HUGE discount? That would be skimming, right? That would be a felony, right? Skimming IS grand theft, right?
