I put my cell phone in my carryon bag like I was supposed to. The lady freaked out and was like "This looks like a bomb". I tersely replied, "No, it's a cell phone". Luckily the supervisor came over right away, point something out to her and she said "Oh!", before I could say what I was thinking. That was "Would I be stupid enough to try and bring a bomb through the front door? No, I would have had someone put it in one of the meal trays!". Figured that would have delayed me a bit... This was like 2-3 years ago.
I like the idea of TSA agents having badge numbers. It's the only organzation with police powers (no matter how you argue it, they are police powers) that does not have serialized identification for their agents.
