A secret customer of Tianjin McDonald's.

Mystery customers come to do questionnaires regularly. If the company intends to do an investigation, the company will send the papers to the receptionists in various restaurants in advance. The receptionist will select some customers to fill out this form and then give it to the head office, usually to the Beijing company. Then the Beijing head office will randomly select and call customers to ask questions about the restaurant environment and dining experience. It will take about half an hour to ask you. Then I'll give you some information about McDonald's and dinner rolls, which are usually sent by mail, and then you can have a big meal with the dinner rolls given to you by the company (free of charge). After eating, I replied to the Beijing head office and became a mysterious customer. After that, you just need to tell the service and environment of the restaurant you are going to.
