I remember your stepfather's shop with all the TT race photos on the walls: seem to remember they also sold cycles as well. My first moped (new) came from that shop and came in very useful on some of the local hills. It sometimes needed a bit of pedalling assistance on the steep bits!

I think the smell (and clouds of smoke) of coffee roasting came from a shop a little way past the current Sainsbury's. The roaster was in the front window of the Home and Colonial, I believe.
