Tableware is a necessary part of the dining process, catering enterprises to provide consumers with sterilized tableware, paper towels and meet the national health standards, is the process of catering supporting services, but also the operator's legal obligations and ancillary obligations, has long been recognized by the community, and agreed upon. The cost of the service is part of the operating costs, as a legal obligation to bear the party, catering enterprises should bear the cost, not because of the tableware sealed package, the disinfection of the costs incurred to consumers, otherwise, it is in disguise to reduce the standard of service agreed with the consumer, in disguise, the transfer of ancillary obligations to the consumer, which is contrary to the principle of good faith and fairness of the civil contract. In addition, the "catering repair industry price behavior rules" Article 8 states: "catering service projects in addition to other state regulations, the operator shall not be charged arbitrarily any name out-of-the-price service fees or other forms of price increases". And numerous consumers are forced to receive additional charges to avoid conflicts with operators when dining, or because of love of face, and their right to fair trade has been infringed upon. Some catering companies in the disinfection of tableware on the packaging printed on the paid use of tips, consumers can also choose to use the charge of disposable disinfection of tableware, the behavior is not illegal? Explicitly informing is still illegal. This is because: firstly, the operator has no right to charge the fee in the first place. Secondly, even if the operator has given prior notice to the consumer by way of a statement or posting a notice in the store, it has no legal effect. Article 24 of the Law on the Protection of Consumer Rights and Interests stipulates: "The operator shall not make unfair and unreasonable provisions for consumers by way of form contracts, notices, declarations, store notices, etc., or mitigate or exempt the civil liabilities that should be borne by the operator for damaging the legitimate rights and interests of consumers. Form contracts, notices, statements, store notices, etc. containing the contents listed in the preceding paragraph shall be invalid." Accordingly, regardless of whether the catering business in its restaurant obvious location or disinfection of tableware on the outer packaging of the clear notification, can not be exempted from its legal obligations.
