Cui Yao is a senior delivery person, but his main job is not to deliver food, but to write negative reviews for others. When someone places an order, he goes to that store to order a takeout, and then writes a "reasonable and irrefutable" negative review about the experience - the temperature of the dish, the integrity of the packaging, the delivery time, and the taste deviation. He scores each item and attaches photos. When merchants see such negative reviews, they usually take the initiative to contact for refund or apology. The client gets compensation and Cui Yao gets commission.
One day, Cui Yao took a big order, and the target was a time-honored noodle shop with an excellent reputation. He went to eat it and got perfect marks for the taste, service, environment and temperature of the noodles. He wrote his first five-star review in his life. The next day, the noodle shop owner found him and said: "Young man, I have been in this business for thirty years, and this is the first time that someone can write a negative review that makes me convinced. Would you like to come to my place as the 'chief critic'? I will make you a bowl of noodles every day. After you eat it, tell me where I can improve it."
