amenity=drinking_water is a place where you can get drinking water. There is no requirement to be able to drink directly from the water jet. Even more, the 'fountain=bottle_refill' makes it clear that this is not possible.
@pietervdvn@Doudouosm@openstreetmap shouldn't this be mapped as a "man_made=water_tap"? It seems pretty hard to drink directly from those machines, I wouldn't map them as a drinking point.
I have some more time. The tag literally reads "amenity=drinking_water", meaning that one can get drinking water for personal use here. It does not imply the physical form of this, e.g. if it is a bubbler fountain or a water tap. In either case, the tagging for the wide variety of items isn't very consistent...
