I remember coming back from Spain on a ferry into Portsmouth. I got taken aside and asked where I was going. I said I'm going to London. The Border Officer literally shouted at me saying, "Why are you going to London?"
My answer, "I live there."
Also I was quite annoyed that I was the only person who got called over by the border officers and I happened to be the only ethnic guy travelling on the ferry. Coincidence?
No offence meant here but....
Of course they are going to highlight ethnic minorties, it would be a bit silly not to. Bit pointless to pick out a blatent white British person. Be like me getting annoyed going to a country where I would be a ethnic minority and complaining for the same.
