We work parking at the Irish Festival. The parking is free, but if you go up with a wad of bills in your hand, they give you a really good tip (especially if I pull me Irish out and give 'em a bit of the mother tongue!). After about 8 pints of Guinness, they give you their entire wallet as they leave!
Also, we work parking cars at the County Fair on contract and work a few other events parking cars; we have it down to a science. Still, the old smoke filled Bingo with the old ladies is a staple event.
