Proč je ulice Mostní přepůlená ?

Holy Cow ! I edited whole world ! I was using local taginfo.openstreetmap.cz / expecting changes in CZ only. Seems that was mistake. Reverting that changeset.
But i still think building=office is appropriate tag, doesnt matter how building is large. building=office exists, offices not. Office can be described more in detail with office=* tag
