I usually shop food at farmers market’s wherever I go in the world. Sellers run out of their fresh produce pretty quickly though, so they’re usually not open more than once or twice a day. I don’t know the statistics, but I don’t think it’s correct to say most people shop in supermarkets; considering the availability of farmers markets and how fast they run out of supply. Higher quality fresh produce at lower prices, vs shopping at a third party distributor like a supermarket? Why would anyone willingly choose that given the options?

Sure, if you live in an industrial small town, there’s probably no farmers market available (I assume, because there’s no farmland or farmers nearby); but most people in the world don’t live in such places, and indeed, most cities do have farmers markets.
