Mineral water

In the South in the States, if you ask for a Coke, the response is something like "what kind?" Because Coke means a soft drink (or soda, or pop as one might call it). Similar in Norway. In some regions, the phrase "mineralvann" (mineral water) means any kind of soda. Which really threw me the first time. I thought I was going to get a Perrier, but instead they kept asking me what I wanted to drink.
