Im confused by what they mean there, even my local garage sells fresh fruit and veg, and sure it helps to live in an area with local shops but we've got co-ops and a bunch of mini market shops all within 1mile walking distance for the majority, though I know some complain about parking still.
whereas 50 years ago when I was living in a really rural area of Suffolk, our nearest food shop was at least 3-6 miles away in the nearest town, we used to have a greengrocers van turn up a maybe a few times a week, and the local farmer sold you milk.
but it feels like now there are alot more general shops selling fresh food/ingredients than there were, its kind of why the old fashioned greengrocers or butchers or fishmongers have kind of died out.
