flew from DFW to SEA last week...as I'm going through security, I realize that I forgot to take out my toiletries. I was going to say "wait" but decided (since I had an hour to kill anyway) to just let it go...and I guess so did TSA.
That's the most common complaint - the lack of consistency.
However, it still amazes me that people don't know about the rules by now (hold onto your boarding pass, take off your shoes, toiletries in a baggie, etc). I was behind a couple of Israelis in Seattle and they laughed at our system.
