I meant explicitly in the context of mapping the larger shop types where 
parts of the business might be entirely separate from the retail aspect 
(i.e. the shop).

For example, where a car dealer (shop=car) has a large warehouse storing 
cars that aren't yet for display/sale. Or where a garden centre 
(shop=garden_centre) also has a private plant nursery where they grow 
plants which will be sold at a later date (once they've matured).

I would think in those cases, these should be mapped separately from the 
main shop area. But only if this is possible to define/know.

Current practice should stand when we're talking about one shop = one 
building.

Unless you think everything should also be included in the shop tag in 
such cases?

Thanks.
