Self-serve vegetables on display on Zhangtang Road in Hefei, East China's Anhui province, Nov 23, 2011. The booth has no salespeople and only price tags stuck to the vegetables for the customer's reference. A woman surnamed Bao, the booth owner, said the vegetables are planted by her family and all are chemical-free. Despite slow business, she said the stall is not to make money but to save waste. Customers take the produce and leave their money, with nobody having ever stolen from the stall. [Photo/Xinhua]
