On the one hand, tourists exposed that they were taken to a restaurant by a taxi but were slaughtered. "Four cauliflowers cost more than 1500 yuan"; On the one hand, tourists want to go to a restaurant for a fast food, and when they pick up the number, it shows that "4538 tables ahead are queuing up"... These two pieces of news push tourists to the hot search for two comparable experiences when traveling outside. Two news related to tourism and catering both involve a proposition: how to maintain the trust of strangers in society. To some extent, the cultivation of such social trust is not only related to the reality of reducing tourism consumption disputes, but also to the important issue of "boosting the consumer market and stimulating consumer confidence". In the dictionary of social trust, there should be no "killing" or "cheating". It is still to be verified whether the "four dishes of more than 1500 yuan" is killing customers. Whether there is a clear price tag is the key. If the information reported by the tourists involved is true, it may be difficult to escape the suspicion of killing tourists. Since the opening of the Spring Festival holiday, many places have been exposed to the practice of killing guests, which is called "revenge killing" by netizens. The so-called "retaliatory butcher" is obviously a stab to the trust of consumers. Under the circumstance that consumers' awareness of safeguarding their rights is increasing and the threshold of online exposure is decreasing, any act of butchering customers is self-destructing. At a small scale, it will label itself as "short-sighted"; Looking at the big picture, it will add obstacles to the revival of tourism and consumption. The causal chain of social trust often presents a positive enhancement loop. During the holiday, there were hot pot restaurants in Chengdu queuing up to 4000 tables a day, reaching a record high. Some restaurants in Changsha also queued up to thousands of tables. In essence, this is the manifestation of the positive feedback effect of trust: many foreign tourists do not hesitate to queue up to talk about crayfish, drink milk tea and eat hot pot, but also because the credibility of those restaurants has been verified - they will pursue quality and cherish reputation, which has won trust and reputation for them, and this kind of trust will arouse more trust. If it is said that cheating on customers is overdraft and damaging trust, the reputation accumulation under the scenario of "4538 tables in front are queuing" is undoubtedly the reverse of cheating on customers, representing the concern for social trust, and trust will eventually become the capital of those catering enterprises, allowing them to reap "trust compound interest" in the snowball. Those who abuse trust will pay the price of not being trusted. Those who care for trust often reap the benefits of being trusted. There is a dividing line between short-term thinking and long-term thinking. The scene in the tourism restaurant is only a microcosmic reflection of the operating picture of the real society. Economic and social operation also requires trust as a connecting belt and lubricant, which is usually two-way. Sociologist Zimmer said, "Trust is one of the most important comprehensive forces in society. Without the universal trust that people enjoy among themselves, society itself will collapse. Modern life is far more based on the trust of honesty to others than we usually know." As for today, society undoubtedly needs more confidence, and one of the bottom supports of confidence is trust, that is, mutual trust ecology. On the premise of having the ability to consume, only if we are not easy to be "routine", can we be comfortable with consumption and have confidence in consumption. Therefore, in public life, there should be less fancy butchering and more "ahead
