This maybe a minor issue but little things can leave lasting impressions.

I was on a MR through LAX last week. I went landside and recleared security through the upstairs security station near door H. This station has never been busy in my experience so I always use it. Last Tuesday was no different. I was the only person in line but the TSA agent was still scanning some stuff belonging to people who had already passed through the WMD. I travel light, no laptop, just a soft briefcase with my reading material and Sennheisers in it. Just as I was about to send my stuff into the scanner a UA FA comes up, pulls my stuff back, and without so much as a "May I?", forces me to wait while she piles her personal stuff into a bin and sends her 2 bags through.

Now I'm not rehashing the old argument of whether or not flight crews should be allowed to cut lines, the point here is that there was no line - this FA appeared to jump in front of me for the simple reason that she could. And by the way, I watched her after she cleared and she did not take off runing as if she was late and the 10 seconds she saved cutting in front of me was critical.
