Not at SFO AA Terminal 3. Just before midnight on Tues 1/25 they were channeling everyone through the Nude-O-Scope, and everyone seemed to be cooperating happily. I threw a wrench into the works by opting out, which seemed to make the WTMD "guard" quite angry. There seemed to be more screeners hanging around than there were paxs, but he quite agitatedly told me that I had to wait until a "male assist" was available. (During the time I was there only one other person, a young lady, opted out). I had deliberately given myself lots of time to make my red-eye, so I waited quite patiently. Had the same experience Saturday, 1/22 for the 7:05am to JFK.
I do not know if my observation is unique, but I had previously thought the SFO screeners at AA behaved with some civility. Now they seem to go out of their way to be rude.
