"The very large, two-story Central Market in Thimphu (Bhutan) bears a strong resemblance to similar markets around the world. What I don't understand is this: if 50 different sellers are selling the identical vegetables at the same prices, how does a buyer decide where to buy his/her vegetables? Do buyers get everything from one place, or do they spread their money around?"
