Fraid he's got you bang to rights really Sleeve wing (Tiger mate and Sprigg). Come on! Sixty quid ain't that much to land and park your plane up and saunter around, it still has to be guarded and all the other things mentioned etc. And yep everyone pays for admission to the event-even ex FAA Officers!!
Perhaps yours and others reputations go before you (snooty attitude perhaps that paying is only for little people, or a tightness for money)? Its backfired totally by 2015.
And I'm sorry,but re-reading your post again...your expectations were wholly unrealistic of the present era.
