Ever noticed people in pubs go to the loo with their beer? Can't they bear to be away from their pint for even a moment. Even worse, have you ever noticed people coming out of the loo with their pint? Wasn't that glass half empty when he went in..?
This doesn't happen in the States, David. Here, you're strip searched before and after your trip to the loo. "Carry a brew...not in the loo!" New anti-terrorist rules. ;^O
