The thing that goes through my mind is "Would you pleeeeese shut up!!!!" Yes, it gets nerve wracking.
And then while I'm stripping, and placing everything on the x-ray belt, the person in front of me starts asking, "Do I have to take off my shoes?" "Do I have to take off my coat?"
People trying to take 16oz bottles of Shampoo, Waiting for the woman in front of me digging in her bag for her ID for 5 minutes.
As I see it, it's a losing battle either way.
