Any time a TSO goes straight for my change I kindly request an STSO summons the airport police or Sheriff's deputy.

I explain that going straight for the currency is highly suspect and I've had the LEO do a count, and after all bag searches I've requested they turn their gloves inside out.

At one Florida airport even the STSO was pressing the TSO for an answer as to why the TSO insisted on screening the vending machine money. Perhaps next time they'll think twice when they want a chocolate bar or money for bridge tolls.
