I find the TSA varies from super polite to rude inbred idiot.

I fly mostly DIA to LAX but like I say they vary.

Last week I managed to leave my watch in the scanner in LAX and they very nicely bagged it and labeled it. I realised 30mins later (flight delay) and went back to get it. They even joked with me about leaving it.

In my opinion it could have easily 'disappeared' but I got it back, sweet.
