Legal analysis: It is illegal for restaurants to collect service charges for drinks brought by themselves. You can tell consumers in advance that there is a service charge. If it is reasonable and acceptable, customers can choose this service. If it is unreasonable, consumers have the right to choose to use the drinks in the hotel or choose other hotels. Because the catering industry is a fully competitive non-monopoly industry, restaurants rely on high-quality dishes, excellent services and preferential prices to obtain good social and commercial reputation. Consumers can choose where they think the price and service are consistent and acceptable, which is completely free to choose.
