At Lax recently whilst waiting in the queue with my crew, to be systematically defrocked by the TSA (COME ON HOW ABOUT A SUITABLE ACRONYM FOR THEM). I was just about to go through the metal detector when a rather obese TSA agent just walked in front of me. I called out 'excuse me', but he ignored me. So I tapped him on the shoulder and said 'Excuse me I don't mind you going ahead, but...' that's as far as I got. He turned around and said. 'Buddy you've just committed a Federal offence, so be careful.' What can you do??????
