I'd suggest that you try serving the same people freshly roasted and ground coffee from a clean french press and pass it off as cheap coffee. Afterwards, serve them the cheapest coffee you can find from dirty coffee equipment and tell them it's high end coffe. I'd be surprised if they don't prefer the "cheap" coffee. The only exception is that some people will actually prefer old, bitter coffee made with dirty equipment because they're used to that taste. Just like some people will prefer McDonalds to a good restaurant because that's what they're used to. Still doesn't make good coffee or food "mainly hokum". :)
