I guarantee that most businesses have nothing against stocking or offering items that people come in and ask them for - but it has to be possible also. If you're asking for a Polish sausage in a hardware store because your neighbour sent you, then they probably don't have the licenses to sell food items, and probably their profit margin is higher selling hardware than selling sausages so they have no reason to start offering them.

There's usually a good reason why a business might not offer something that people think they should offer. Usually it is that they can't be profitable enough at a price point which customers will accept.
