The fuel station - you added the "building=service"

We don't map fictional things. In OSM you have to stick to physical reality on the ground.

If you wish to map the building, you can map the roof, you can map the office, such things.

But the way to map the amenity fuel station is to map the whole area as such - but that doesn't mean the whole area is a building.
