I entered the US last Wednesday at Dallas, went through security for internal flights at Dallas on Thursday and Dayton, Oh., on Sunday. I found the procedure far less painful than going through LHR! Admittedly, LHR immigration is never a problem except sometimes for the queues, but the security lot could well, in my experience (15 times through LHR this year) usefully learn from the TSA in DFW and PHX - I don't know about elsewhere.
LHR T4 suggested I take my belt off. I pointed out that mytrousers would come down, and they rapidly changed their minds, commenting that they thought it would not be a pretty sight. How right they are.......In any event, it didn't set the detector off.
I suppose it really is 'YMMV'. But I must have been through TSA security some 30 or 40 times with only one problem - they asked what I had in my bag, and I said 'Just a torch'
In American, 'torch' = 'blow lamp' In English 'torch' = 'flashlight'.
Just as 'rubber' = 'condom' and 'rubber' = 'eraser'
'dyke' = 'ditch' and 'dyke' = 'diagonal side cutters'.
' momentarily' = 'shortly' and 'momentarily' = 'for a short period of time'
Two nations divided by a common language!!!!!
