Did you know?
The floor numbering system differs significantly between American and British English. In American English: "first floor" = street level (what the British call "ground floor"). In British English: "ground floor" = street level; "first floor" = the level above the ground floor (what Americans call "second floor"). This is a famous communication error for American tourists in UK hotels, who go up to the "first floor" thinking it is street level and end up on the second floor instead.
