I was once delayed like 10 hours, so I thought I would have a little fun.

I decided to go through security a lot getting diffrent screeners, and giving them a hard time about taking off my shoes. (I know, I have no life.)

I was surprised because I would keep leaving then, come back, and leave again, etc...............................

The guy watching the exit was like are you okay because this is about your seventh time leaving. :-) It was not a TSA agent, but a private security person. Goes to show you that they may be doing a better job then the TSA.
