Adding さん to places


I have recently come across text which adds さん to places. For example,
bookstore is ほんやさん. Is this normal, and in what context?




ほんやさん usually means "bookstore owner/worker", but CAN mean the store itself.
Adding さん like that to a business name is a common way to refer to such. ほんや =
bookstore, さん referring to the person.

On the other hand, mountains are often referred to, ending in さん, and still
refer to the place, eg ふじさん = Mt. Fuji. However, this is NOT the same さん. In
ほんやさん, the さん is the person-name-honorific さん; in ふじさん, it is 山 with a reading
of さん. These usages are not related.

Edit: Sorry, apparently, with さん it can STILL mean the place. AFAIK it does
more often refer to the person, but you'll have to divine it from context to
be sure.
