I never thought I'd meet anyone who doesn't know the meaning of WC until I traveled to Europe with an American. So for those who don't know this either, never ask where is the "restroom" or "bathroom" when you are in Europe. You'll either get a blank stare or a weird look. In Europe, the correct word for restroom is “WC”, an abbreviation for Water Closet. You'd have to pay 20 cent- 2 Euros to use
