This drives me insane. I often use OSM for things like "show me all sources of drinking water along this route". But you need the magic key word.

In this case, it's certainly not "drinking water (food) and not "drinking water (tourism)". It's also not "water tab (service)". "Fountain" works mostly OK (since fountain water must be labeled as non potable by law here if it is), but sometimes the fountain will be a tiny bird bath in someone's back yard.

It's so stupid, OSM has data on publicly accessible drinking water, I know because I add them. There's even meta data on whether there's an explicit sign "potable" or not. I just haven't found that magic key word to display them.
