[OSM-newbies] Nodes v. Ways when adding amenities

[Tac Tacelosky]

"A circle would imply a circular building."

Only if it were tagged with building, right?  Suppose it was only tagged
with non-physical attributes, like shop=grocery?  Would square be any
better / worse?

On a related note, when creating ways for businesses, my gut feeling is to
surround the entire property, not just the building.  This is especially
relevant for gas stations, where the building itself is often tiny, and for
that matter the building is often a convenience shop with sells candy and
maps, and will take your cash if you didn't pay at the pump.  But the "gas
station" to me seems like the whole property.
