Legal analysis: At present, there is no clear regulation or clause that restaurants can or cannot charge service fees. The price of catering industry belongs to the category of market-regulated price, and enterprises have the right to set their own prices (whether acceptable or not), but the premise is that consumers as service providers should be clearly informed in advance. At present, what the price department can supervise is not whether the service fee can be collected, but whether the service fee is clearly marked. It is unreasonable not to inform in advance. Consumers enjoy nine rights, namely: 1. The right to know the truth. That is, consumers have the right to know the real situation of the goods they buy or use or the services they receive. 2. Choose independently. That is, consumers have the right to choose their own goods or services. Including two aspects: first, there should be sufficient choices for commodity varieties, service methods and their providers; Second, the choice of goods and services and their providers should be free and not forced. 3. Right to personal and property security. That is, consumers have the right to buy goods when their personal and property are threatened. 4. Trading rights. It means that consumers have the right to obtain fair trading conditions such as quality assurance, fair and reasonable price and accurate measurement when purchasing goods or receiving services, and have the right to refuse compulsory trading by operators. 5. Legal claims. The right of claim refers to the right of individuals or collectives to claim compensation when their rights and resources are infringed or lost. 6. Right to know. That is, consumers "have the right to acquire knowledge about consumption and the protection of consumers' rights and interests." 7. The right to establish consumer organizations. It includes two aspects: first, it has the right to ask the state to establish a functional organization representing the interests of consumers; Second, they have the right to establish their own organizations and safeguard their legitimate rights and interests. 8.
