A thought. We have a good market in Tooting with fish, butchers, tools, clothes, food, phone, pets, etc. It seems busy and well used. In most parts of London, that I have seen, farmers markets are set-up as a separate ghetto for middle class people to wander around for bits and pieces before they go Waitrose. If stalls became free in Tooting market could they be occupied by people selling as local as possible produce?
