I heard on the radio that some people are able to "tip" TSA staff and get a less-aggressive pat-down. They fold a $10 bill so the 10 is showing, and hold it in front saying how much you appreciate all they are doing to increase air security. If they take it out of your hand, you should get better treatment. If they don't, then you won't.
I don't suggest trying this as I think there would be legal issues, but it is an interesting idea.
