I remember once going through the non-EU queue in Manchester, when the (black, probably Nigerian) guy in front of me got a bit of a going over about his visa status, until he broke down, then the agent discovered that he was a UK permanent resident as she was flicking through his passport and she realised he'd been turned away in Amsterdam (seems on a family visit). Anyway, the mood changed in an instant, he got a hug and advice about how to make sure the trip would work next time. It was nice to see a human response in such a situation.
