Although very common in practice, I think tagging the whole business on 
the building is wrong, and treats OSM as a commercial directory, rather 
than a map.

Mapping as a node is only appropriate if you don't know the physical 
extent.  Otherwise, for the business, I would map it with the business 
type as main tag, or as a building part, if possible.

Note that it is very common for the extent of the business to be more 
than that of the building footprint; a significant part of the pavement 
may actually be private land, available to the business.  I'd go as far 
as to say that that is true of most high street shops.
