1. The catering industry forces consumers to charge "tea space fee". When they eat, they have a contractual relationship with the restaurant based on consumption. The contractual relationship should be based on the freedom of contract. Consumption comes from demand, and consumers can choose whether to buy tea or accept the "tea space" service. On the premise that consumers have no demand, the restaurant forces consumers to buy tea and pay even if they don't drink tea, which completely restricts and deprives consumers of their right to choose independently and trade fairly. Second, the "overlord clause" in the format contract When consumers apply for various membership cards, sign subscription books and service contracts, operators often sign clauses for consumers, which are drawn up in advance by them and not negotiated with consumers when concluding contracts. "The power of interpretation belongs to the operator" is precisely that the operator takes advantage of its dominant position in the market, which violates the principle of fair trading and limits the rights and methods of consumers to interpret the contract. The content of this clause is invalid, and it cannot be exempted from the legal responsibility that the operator should bear by seizing the power of interpretation. Third, restaurants are forced to "scan the code" to order food. When consumers go to restaurants, some restaurants do not provide manual ordering or even on-site menus. Consumers can only "scan the code to order food" after paying attention to WeChat official account or applets. Because of the complexity of smart phone operation, scanning code for ordering food is not universal. The elderly and minors often need the assistance of others to complete the order scanning process, and there may be problems such as personal information disclosure and even payment security behind the "code scanning". Fourth, the operator refused to provide services. Consumers bought the services of the merchants by group purchase, but when making an appointment, the merchants refused the consumers on the grounds that the number of reservations was full and exceeded the reception capacity of the merchants. When negotiating the date of use with consumers, the merchants shirked for various reasons and did not provide the agreed service. In the end, the group purchase coupons purchased by consumers "hit Shui Piao".
