Re: I'm a US citizen
The TSA agent was professional, friendly and chatty and far better mannered than the goons who greeted me at Heathrow.
"Heathrow? This is TSA Boston. Hey listen, we got a guy named Mark Jan on his way over to you. Yeah that's him. Hey listen, he asked for a pat-down rather than a trip through our body-scanner, and he had this weird look about him as we did it. You might want to give him some extra attention when he arrives".
