there is no rule that charges are not allowed. So it's legal. In the civil field, the law can be done without prohibition! If consumers' right to know is violated, such as not indicating the price, then they will be charged! You can complain!

: According to Article 8 of China's Food Hygiene Law, the hygienic conditions in the process of food production and marketing are as follows: "Tableware, drinking utensils and containers for direct food must be washed and disinfected before use, and cookware and utensils must be washed and kept clean after use." It can be seen that providing sterilized tableware and paper towels to consumers is a supporting service project in the catering process, and it is also the legal obligation and incidental obligation of the operator. It is not possible to pass on the disinfection expenses to consumers because the tableware is sealed, which violates the principle of good faith and fairness in civil contracts.

In addition, China's "Rules of Price Conduct for Catering and Repair Industries" also stipulates that "unless otherwise stipulated by the state, operators of catering services shall not charge any extra-price service fees or increase prices in other forms". So there should be no charge for disinfecting tableware.

according to the regulations of "business norms of catering enterprises", the charge for disposable sterilized tableware has been listed as the category of repeated charges for catering enterprises under various pretexts. China Consumers Association also made it clear that catering enterprises have the obligation to provide consumers with tableware that is qualified for disinfection, and bear the corresponding disinfection costs, and shall not pass this on to consumers.
