In Germany I think I saw a dedicated drinking fountain only once. There are of course fountains, but most of the time there is a sign on them saying "Kein Trinkwasser" ("no drinking water"). We have exceptionally good tap water and I think only very few Germans fear to drink it. I notice it every time I brush my teeth in another country, it just tastes bad. So they got us with another trick: Germans are just used to sparkling water.
