Interesting! The only time I have EVER been hassled was in Charlotte and that was in the late 90's. We were visiting my family for 2 weeks. DH (UKC)had an old work visa, which was no longer valid because i had been replaced by a new visa class, but we didn't know that. In any case, the IO started giving BOTH of us a hard time, and scrutinized my passport because it was issued in my former name, with the official name change entered on page 23 (I'll never forget that). The IO couldn't seem to find the name change, so I said "page 23". He then started grilling me about how long I intended to stay, and why I was traveling to the US. We kept calm and finally got through, but it was NOT fun.
Now, to put this in perspective, at the time we were both over 50, had limited luggage, were resident in Portugal, had return tickets a flight 2 weeks later (on Christmas Day, as it happens). I still maintained US bank accounts because I periodically returned to do consulting work, so even finances weren't an issue.
That particular IO was just nasty, and I've always thought he was an example of someone who had been promoted to a position that he should not have held, and used his 'power' to abuse people. I have reasons for my opinions which I will not express here.
