Let them do their job. That doesn't involve counting out money. This nonsense that somehow they are hard done by? Give me a break. They have absolutely no business, no more than anyone else in any job, exceeding their brief. The amount of money anyone has on them is not an issue for airport security. End of.
I am polite and courteous to anyone who offers the same in return. But if some guy or girl is going to pick on me for whatever reason and in a way he or she has no right to then damn skippy I'm going to stand up to them.
