My experience of such stores is just the opposite. When I don't care what kind of <something> I get, I just go to the supermarket or buy whatever is cheap on ebay. The choice takes a couple of minutes.

When I go to a specialist store, which I do every so often, my choice has been made before I walk in. That's why I'm there; because I already know what I want, and I know that I can't find what I want in the supermarket or by trawling eBay. I'm just hoping the specialist store has it or can get it. I spend less time choosing in the specialist store.
