For two years, Sun Jianming has run a food stall outside the industrial park. He treats Lin Zhixia, a regular customer, to the so-called regular-customer price of 22 yuan, while charging new workers only 18 yuan and giving them a braised egg and unlimited beef. When Lin Zhixia confronts him, he snaps, 'If you think it's expensive, don't eat here!' She dumps the entire bowl of noodles and cuts ties with him for good. Across the street, at Chen's Noodle Stall, the young couple Chen Yuening and Zhou Jing'an serve generous portions at the same price to everyone. 'Treat every customer as an equal' is the very foundation of a good bowl of soup. The scales in front of a humble street stall have never weighed just noodles, but a person's conscience.
