Ah, sorry yes, that was bad phrasing on my part. By normal I meant what was on the menu (water that is branded, bottled, shipped, sometimes stolen) instead of my out-of-the-ordinary request (tap water), but calling that the 'normal' is of course a culture-specific way of thinking, and a cultural feature I do not like.

In these places where bottled water is the norm, do you have to specify what brand you want? Like if they ask what you want to drink and you answer "I'll just have water", is that an incomplete response?
