Poor service attitude is a mistake of business model. Customers have not found any health and product quality problems in their consumption, so there should be no public department to complain. However, if you are not afraid of trouble, you can ask the manager. Good operators are not allowed to make such mistakes in their own shops. If it is really their problem, they will definitely actively solve or compensate. However, if the operator doesn't care about the quality of service, I don't think you need to bother with him. number
