I think it depends on all sorts of things, we’ve travelled through London, Oxfordshire, Gloucestershire and we’re currently in Warwickshire heading North. Most stores I’ve seen very few problems, but I went in a couple of Co Ops in small villages and there were gaps in the produce sections. The worst stores for empty shelves? I went in a Savers (hard discounting toiletries & beauty store), in Banbury last week, I’d say 2/3 of the shelves were empty. I bet they don’t pay their drivers much or are shit to work for or both.
