In general, a slimming shop needs two store managers and 4-5 waiters to serve customer service manually every day, and most of the profits are paid for labor costs. Thinking of close friends is different. The service of the project is a combination of technology and instruments, which saves trouble and effort, so two people in a small shop can serve four or five people at the same time, and it doesn't need too many people to open a slimming shop.
