Many sub Post Offices in my area have gone, quite a few because of the grotesque actions taken by Post Office management who refused to accept that the wonderful computer system they had introduced at great cost had huge flaws, instead preferring to believe that so many sub-postmasters were either totally incompetent or out and out fraudsters, usually the latter. It is scandalous that no P.O. top management were dismissed for their actions, with loss of pension rights. In many countries some would have faced criminal prosecution and jail, just like those Sub-Postmasters.
Now we have a P.O. in WHS that, in theory at least, is not able to be reached by car, or have P.O., Royal Mail or Parcelforce vans reach it, for most of the working day because of spurious 'climate change' prohibition of vehicles anywhere in the area. These restrictions are ignored by many, so you still get the diesel fumes etc, but if you parked, even with a disabled badge, you could get pounced upon for a £50 fine.
