A street vendor shamelessly exploits longtime regular customers and acts outrageously arrogant! Shen Zhou, a factory supervisor, discovers that the meat stall he has patronized for three years gives discounts to new customers while consistently charging him higher prices. When he confronts the vendor, Liu Guihua, she not only argues irrationally but also dumps food in front of everyone to humiliate him. Disappointed, Shen discovers a stall run by a husband and wife near the back entrance, where prices are fair and the ingredients are honest. He awards them an order for 80 late-night meals for the factory's night shift. The couple runs their business with integrity and carefully prepares the order. Upon learning the news, Liu Guihua becomes resentful and begins plotting to sabotage them.
