London Waterloo has two key characteristics at morning rush hour. 1 - It's the last stop 2 - The train carriage is crowded. (Because it's the last stop)
Why then, do people insist on performing that whole ritual of whispering "excuse me" and then trying to squeeze past you as the train pulls in? Everyone else has to shuffle around so that this muppet can get off.
I always feel that I'd be justified in smacking this person across the head, and tipping their briefcase out onto the platform and explaining "IT'S THE LAST STOP! We're all getting off here, Spanner. You show me one person who's staying on and catching the train back..."
