Hmmmm interesting, but are they thinking that because of the size or because of the decor etc. You can't always tell what people are really thinking.

As for other shops coming and going, is that really because of their location? Or how they run their business?

Your shop may well have been there so long because it's good at what it does and caters to a certain market and that's what makes it a winner.

Loyal customers would follow you if you moved.
