From a ways back...
I'm ... erm ... attention impaired, severely so when under stress. I am either off in my own little world or so hyperfocused on the task at hand that I frequently blow right by people talking directly at me.
Me, too, and it's part of why I have issues with the TSA, even without the NoS nonsense.
How in hell am I supposed to remember all the minutia they want me to remember? I have to disassemble all my toiletries and repackage some of them, but not others, a certain way before the flight; there are some things I have to take out according to specific procedures or not take out according to specific procedures; there are some things I'm not allowed to bring at all, but others (that appear far more dangerous) which are just fine; there are some things I can wear and some I can't....and these rules and regs not only change frequently but they're not consistent across checkpoints.
I run the risk of getting arrested if I don't do all this correctly, and at the minimum I'll get barked at by some fool who got his job off the back of a pizza box.
Great.
