Airport and Security Stress

As a frequent flyer traveling to speak at corporate retreats, I try to be cognizant of my triggers for stress, particularly going through security.
Historically, Customs and Immigration were famous for creating stress but in recent times, the dubious honour of first prize has been awarded to Security.

I know the rules. I had everything in order. I was just about to enter the fast track lane when a first time flyer was directed in front of me.

He was clueless to the intricacies of the new rules, and apparently deaf and unable to read. He held up the line and thought it was funny. I took a deep breath and tried to be patient but we really need an efficient system put in place at airport security, because even I have my limits! What do you think?
