I dropped my drivers license in the hotel room while we were leaving and didn't realize it until getting to the airport at SNA.

I was nervous and upset, but three TSA agents just asked me a lot of questions and were very helpful. One asked if I had my Costco card with my picture (I didn't). Then an agent asked if I had any medication vials showing my name. I showed them my vial for Crestor and they said everything was fine and I could proceed.

They didn't even open my luggage for an extra check or anything.

I think the location made a big difference though. I really doubt they would have been as nice or even let me board at LAX. I've always found the SNA TSA people to be very polite and friendly.
