First thing's first, I don't consider myself to be one of the screeners most people think of when referencing TSA. I try to be as cool and understanding with passengers as I can, respecting as much freedom of health and privacy as is in my means.
Also realize, most of the people I work with and myself know how the real world works. Most of us know that we're not saving the world (we make fun of the people that think so), and that the VAST majority of travelling public has no ill intentions.
EDIT 1: I have to go to sleep now. I'll answer any unanswered questions when I wake up!
