To continue the never-ending saga of British oddities (since it literally has no end), let's dwell on some quirks that set this delightful nation apart from my own.
First Floor—No—Ground Floor
Navigating a multi-story building can be a bit tricky for an American in Britain. If the bookshop is on Floor 1 then that does not mean it is at street level. Neither does Floor 3 sit on top of just two other floors. In this country the ground floor is regarded as Floor 0, the next floor is 1, and so on. So on your next trip to London take your time in the lift and double-check that you really want to go up 16 stories and not 17.
