Funny thing about those complaint cards. They could also be used for compliments - if they could be found.

I transited a checkpoint Sunday AM. The TSO on the other side of the belt who was rearranging everything said 'thank you' to me because my kippie bag was out and sitting on top of my rollaboard. I said, 'Thanks for not barking. I'd put in a compliment card, but I don't see any around and I don't have time to wait for a supervisor to get me one. Maybe next time'.

It's true - I did appreciate not being barked at, and there were no compliment cards anywhere to be seen. He said he could get a supervisor down 'really quick', but I said I had to catch my flight, couldn't wait (also true).

Besides, I know the supervisor will insist on seeing my ID before giving me a form. Are they readily available at your checkpoint, eyecue?
