Why do many stores recruit salespeople all the year round?

Let me look at it from another angle: Wang Po sells melons and boasts. Put up a recruitment poster at the door, indicating that the store is busy and needs help. In this way, customers will have a sense of trust and think: Wow, this store has a good business and the things must be good. Go in and have a look ... Buy!

In this way, the shopkeeper makes money.
