I have to differ. I lived and worked in Europe for ten years. The worst part of any trip home, which i did at least twice a year, sometimes more, was dealing with (1) US Passport Control and (2) US Customs. Always a pain and they give you the third degree, and I am a citizen. The worst in Europe was Ireland, always got the third degree there too.
I GIVE THE EUROPEAN TSA NO PROBLEMS WHATSOEVER . I WILL NEVER TRAVEL THRU FRANKFURT DUE TO THE WAY I WAS TREATED!
