That is pretty universal. Same sort of people that blow up and a poor minimum wage store clerk when there is something not in stock that they want. I have been pissed off at airport staff before. With good reason a couple times. But I swallowed it hard and was tolerable to them and ended up getting where I was going. I hate self inflected stress. Which covers most stress in the world.
I use to breeze through security but now with the taking shoes off thing It takes longer. I am going to have to start flying in house slippers.
These are my newest acquisition for sprints across ATL and DFW:
Slip-on shoes. :-)
And a jacket with zillions of pockets. I carry ~everything~ in my jacket and nothing in my pockets or on my belt. slip off the jacket and run it through the machine... slip the shoes back on and... presto.
the only time I've been wanded in the last couple of years was a time that my hand accidently brushed the metal detector as I was passing through it [sigh] twice. That tweeks out the machine, I came to learn. Now I make sure to keep my hands in front.
