Right. It's great to map amenity=drinking_water on a node at the exact
position of a drinking fountain or water tap.

But if you want to say that a leisure=picnic_site has access to
drinking water without creating a separate node, then use the approved
and popular tag drinking_water=yes on the same area or node as the
picnic_site.

The key drinking_water has been used over 60,000 times and was
approved in a well-developed proposal back in 2014, so I picked this
example for the page.

But if there is a better example (eg atm=yes and amenity=atm?) feel
free to change it.
