Thinking about this - the inner Briton likes nothing more than setting up a small shop selling stuff to other people. It hardly pays, you live off bank finance, and it's risky. And yet, so many aspire to doing it.
Me - I'm boring - a bookshop with tea and coffee facilities that's open in the evening, and a large selection of imported books. I'd do fast ordering and home delivery by bicycle.
So, if you were to run a single shop (i.e. not a chain), what would you sell and why?
