My country is what it is, a place where that demographic of old and female does not have much technical knowledge because society has traditionally discouraged it. So when you see a store with aisles full of tools and building materials overwhelmingly hiring that demographic -- and workers who are indeed unable to help customers much -- it does seem strange and one wonders at the reasons that the company's management has in mind. Are wages so low that only this demographic would accept them? Is it merely an anti-shrink measure? Are profit margins higher on the products (e.g. gardening) that they do know much about?
