I guess one of their hallmark is the quizzing one goes through by the TSA to figure out if you have had a bad day or not. I never have the inclination to spend time chatting with the psychiatrists aka TSA.
I have asked myself everytime I get picked "randomly" to be groped, is it worth being humiliated in this fashion just to earn a living? Even if I quit flying they are chasing every other means of transport. It will not be too long before they setup a table on the freeway to search cars.
