In most of Western Europe, bottled water (at very reasonable prices) is consumed at a higher rate than in the USA (since tap water is not as easy to find).
I'm aware. I lived in the French Alps for two years. In every place I've traveled within Europe, I've found it easy to locate public water fountains. Of course, most of the American tourists preferred to buy bottled water from the illegal sellers at a ridiculous price because they were scared to drink from the fountains. Me, I just keep a collapsible bottle in my bag and fill up at fountains.
