(I very nearly put this in "Games")
I was browsing a remote Coventry suburb on Google Earth looking for a parade of shops which I used when I was much younger and staggered to find a shop selling electrical appliances! I can see how the rent would be attractive but the chances of anyone in need of an apppliance searching for that particular street are pretty low I would think?
That got me to thinking just what kind of service does every suburb need that someone wouldn't normally journey into town or to a supermarket to find?
Off hand I thought of the following:
Newsagent
Off-licence
Post Office
Fish & chip shop
Launderette
Dry cleaners
Bookmakers
There's probably some obvious ones I haven't thought of yet?
