When I was returning to the United States from Croatia, but in Heathrow Airport, my wife and I got picked for a secondary interview at the gate with a British Gentleman who asked me and my wife very detailed questions. My wife had just changed jobs, so her inability to give the corporate address of her employer made her interview take twice as long as mine. He had a hard time understanding that while a hospital was based out of Alabama somewhere she worked in Missouri and she didn't know a lot about their Alabama operations. All those questions made us very nervous but once through we saw no more problems.
