Oooh. *raises hand*
My favorite UK Customs story:
Several years ago, I was arriving in London from Moscow with a large group of football fans on the way to a match. Some of them had brought 2 cases of vodka along. Special edition stuff. Good vodka (I've still got a case from that same batch, saving for a special occasion!).
So, one of them is wheeling the cases on a baggage cart and starts to go through the green corridor. I look back, realize this is happening, and start quietly freaking out. I tell them to stop. I'm thinking - this is surely above the bottle limit for the 4-5 of us standing there... who else from the flight can we grab and have claim part-ownership? And how screwed were we since they were already halfway through the green channel with two obvious boxes of contraband? (I think there was even branding on the side!)
One of the Customs guys walks up... I'm thinking this is it, We're all screwed. On top of the boxes was a small stack of football fanzines. He can't understand us as we're conversing in Russian, but he figures out what's going on. He picks up one of the fanzines and says...
"Ah, don't worry. I don't care about your [boxes of] magazines. Carry on through."
Much scolding of my mates, followed by much laughter followed
