In the process of service, you can't use language like "I told you so", which is written into the specification. In recent years, the state has paid special attention to the improvement of the service level of the government service window, which is a good thing. Although there are still many irregularities and unsatisfactory places, the overall service level of the window has been significantly improved. Whether there should be a service ban on window services has been controversial. If there are too many taboos, we can't exhaust them. For example, breaking the law and discipline, not swearing, not swearing and so on. If all this can't be said, you can write a thick book, which is completely inoperable. Therefore, many people and experts believe that there should be no taboo, and what to do and how to say should be standardized, instead of telling window service personnel what not to say. This view seems reasonable, but it is also absurd in essence. First of all, it is impossible to cover all service links, and it is impossible to exhaust all possibilities and scenarios. Therefore, no matter how good and perfect the specification is, there will be dead ends and places that cannot be covered, which requires service personnel to do a good job of service and explanation according to their own subjective understanding. If they operate in full accordance with the norms and do not give the window service staff some room for active service, it is impossible to do a good job of service. Secondly, each industry has its own characteristics, and over time it will form a specific vocabulary and language environment in the industry. These words and languages often have some languages that the service staff can't feel, but they are very inappropriate, uncivilized and even hurtful. Therefore, it is necessary to stipulate the prohibited terms according to the specific language environment of the industry itself. At the same time, don't extend the forbidden words outside the industry language environment, and don't have infinite association with the industry language. Therefore, it is feasible and operable to ban only the commonly used words that have been formed in the specific language environment of the industry itself. Just introducing the forbidden language in this industry does not mean that you can speak illegal language, nor does it mean that you can swear. Finally, due to the frequent changes in the prohibition clauses, it is suggested to make some flexible provisions in the specification. For example, specific prohibitive clauses should be listed on the website or other appropriate places regularly and irregularly by relevant departments, which is more flexible, operational and effective.
