Back on the subject of high streets, those in Britain's larger towns tend to be somewhat depressing - so many now look almost identical with the same shops and an entirely homogenised appearance. Reuben mentions pedestrian areas, which is very much the case these days, certainly in bigger places.
High streets in the smaller towns and villages tend to have more local shops. Our town is a case in point - only the rather small Co-op is part of a big group. There was, until a few weeks ago, a branch of the giant Ladbrokes bookmakers, but that has now closed down. We did, a few years ago, have two banks in the High Street, but both are now closed. The last one, a TSB, shut last month. They even boarded up their cash machine.
There are some worrying signs. Until recently, we had two bakers' shops in the High Street, but both of them have closed down. A new (and rather expensive) artisan bakery has appeared, though it only opens on two days a week. It's not all bad news - we have an excellent greengrocery and while we have no use for the fishmonger or butcher's shops, I am told they are also very good. We also have Grain & Sustain, a "refill" store where you can bring your own container and fill it up.
Our High Street has a plethora of cafes, hairdressers and barbers for some reason. It's hard to imagine that all of these will survive. What we have seen, though, is that those people who have put in some time and effort (and doubtless money) can do well, so there is some encouragement to be had.
