I fly a lot for work. Lots of it is international. I have global entry and TSA PRE. Global entry would be nice if they had not screwed up my records. It is now worse that getting in the long line. PRE is worth every penny.
Several years ago they were doing training on the scanners at Logan. My wife and I were "lucky" enough to get selected. My wife didn't realize she had a tissue in her pocket and ended up getting an angry TSA agent doing a secondary screening on her. This included essentially a karate chop movement up her crotch. Super painful, over the top and completely unnecessary. There isn't much you can do if you get a crazy agent. They can keep you around until your plane is gone and cost you a fortune.
Fortunately for me, some of the public backlash has had an effect on the TSA management and I have noticed a distinct change in attitude that last few years. This effect has been magnified traveling out of DC since these guys know that you could be a congressman or senator or one of their staffers. They are probably the only ones who could truly get them fired.

Anyway, I do my best to be polite and friendly and follow their directions. I have had no real issues. I have learned not to ask questions or rock the boat because it will always result in keeping me from getting to my plane. It isn't fair, but I need to fly a lot and it just isn't worth fight the fight every time.
