I had the exact same experience at SEA several weeks ago: I waited well over 30 minutes, had to remind the TSA officer numerous times that I was still standing there. He was not bothered one bit that I'd been standing there for so long. Which is rude in and of itself. Then some other TSA officer walked by and started talking to the one in my security line. Just some chit chat. After 5 or so minutes, he started asking why I didn't want to go in the machine. Did I realize this was not an X-ray? Did I realize that this was in fact perfectly healthy? Then, after letting me wait another few minutes, this same TSA officer took me and performed the search ritual, not hurried one bit, doing everything with the greatest pauses, all the while chewing extravagantly on his chewing gum. If that's not unprofessional, then what is?
