When I was a child, each counil Estate here had a little row of shops which included a butcher and a greengrocer. At the bottom of our road was a little Market Garden where we might have to wait while the owner dug up some spuds and cut a cabbage. We had four farms within the town's boundaries. Later we got a small shopping area in the town centre (as much as we had one). I remember four butchers (Wests, Dewhurst, Baxters and one other) and a wet fish shop. Now we have Asda, Sainsburys and a lot more houses and tacky flats. No farms, no greengrocers, no fishmongers, no bakery. (I don't count Greggs as a bakery or even a food shop!)
As far as possible I grow my own veg and fruit. Nearly 60 years ago I got an allotment and have hung onto it (although the original was built on and I had to move to a smaller replacement). It would take 6 years or more to get one now. It supplies me with fruit and veg for a couple of months plus some gets frozen and excess fruit becomes jam or gets bottled.
I don't buy Avocados. I don't buy Kenyan beans or Moroccan mangetout or Spanish Strawberries. I go without if I can't find or grow UK. I never buy those tasteless, hard, red objects they laughingly claim are tomatoes or the cricket balls masquerading as peaches. My Apricot tree died last winter so I have bought a Peach tree.
We do have a butcher at the far end of town. I occasionally buy from them if I am in that part of town (rare) but I would have to order Rabbit - only available as selected joints - and pigeon is not available at all. Their meat is good, mostly British produced, but horrendously expensive.
