Oh yeah on a side note... When I went on my trip to London I went in to a Starbucks (ahhh yes, a familiar site so far from home!) and asked if I could use the restroom. The chick behind the counter looked at me funny and was like "use the wha???" lol. I said "the restroom...??" and she again kind of gave me a blank stare. Finally another employee came up and was like "Oh he means the toilet".
It was just funny to me because we never say that usually. It's always restroom or bathroom. Toilet, to me at least, is just a raunchy word. I'd never imagine going in to an establishment and asking where the toilet was, haha.
