How to tag a bank that does not offer service to the general public?
I just tagged the WestLB building in Düsseldorf, Germany, which is the headquarters of a large commercial bank ([map link][1]).
I tagged it as `amenity=bank`, `name=WestLB`. However, I'm not sure this is correct:
The [Wiki][2] page for the key "amenity" says:
> the primary tag for useful and
> important facilities for visitors and
> residents: toilets, telephones, banks [...]
So this seems to imply that `amenity=bank` is only appropriate for branches that offer retail banking (like ATMs, personal bank accounts etc.), but not for bank offices that only server large institutional customers.
So is `amenity=bank` still appropriate here, or rather something like `office=bank`, or `office=financial` (or something else entirely)?
