Legal analysis: there is no legal basis for charging service fees, but the law does not prohibit it. There are no hard and fast rules in law, but there is a tradition of historical practice. The service charge is brought by foreign-funded star-rated hotels that settled in Shanghai after the reform and opening up, and the additional rate is 15%. At that time, the price department also approved it, and now it doesn't need the approval of the price department. Legally speaking, the behavior between civil subjects can be done without prohibition by law.

The so-called restaurant service fee also follows this principle. At present, the government has not set a unified price for how much service fees to charge. Operators should inform consumers in advance of collecting service fees, and the notification method should be clear and clear to ensure that consumers know. Whether the operator has effectively fulfilled the obligation of informing should be based on whether the consumer is actually informed.

If you only use inconspicuous fonts in menus, desktop labels or somewhere in the store, it is not enough to attract consumers' attention, and it is only when you check out that you have violated consumers' right to know.
