DH finds European customs, 'not very serious". Minimal questions asked, more or less a "wave through". When he returns to the US however, he is often asked very direct questions; "What was your business abroad". "What kind of physician are you?", "What meeting did you attend"? etc. Most of it is disguised as conversational banter, but they are observing all of the time. He feels that type of questioning is far less in Europe and Italy by far, is the worst in terms of security and customs. In the US, they found an M&M in his pocket during a pat down. The same M&M that was ignored in a European airport.
Wow. Never went through a US "pat down" upon my return to the US from London last year! Was just asked for my Passport and declarations form. No other questions. This was GTW - ATL. Now, going through Security in London was an adventure! Went through a "pat down" there, and had to go through the booth with the air poofs and the wipe-down of my laptop. My n/s flight was on Delta. Very different experience!
