I finally flew a domestic segment out of IAH a couple of weeks ago and got my first three beeps (both GE and elite on UA not sure which made it happen)

I actually got a small lecture to put my coat back on. I had already removed watch, wallet, phone etc and stored in my coat before hte check point. They actually did not have any bins available to use and the TSA "girl" was huffy because she had to go get me a bin to run through the machine, but it was a very easy experiance versus normal TSA feckless nonsense.
