In my opinion brick & mortar record stores that do not care to be kind and gentle with their customers (incl. by imposing them rules that can be taken as embarrassing or rude), strongly prefer to do their business with Discogs and eBay and just maintain their stores open just to attract people who want to sell their collections to them. In Athens at least this is a verified fact. In one of these stores there is a "hidden" attic where almost nobody enters to browse. I have been once. Really impressive. Surely 30.000,-- records therein. Whenever a customer enters with a want list, the owner may enter the attic, checks availability, and offers the then-actual Discogs price.
