post_office=bureau is probably incorrect. Since post_depot already includes services like frontdesks. Sorry for that.

Just to clarify: although there is already the “PIN AG – Depot Wilmersdorf” tagged with the amenity post_office, the Wilmersdorf depot is technically also a post_depot. We sort letters and parcels there and then deliver them. However, it could still be considered a post_office, since they also provide certain customer‑facing services, such as allowing people to pick up letters or parcels (for example when a mailbox is broken).
