Do salespeople usually have work clothes?

Salespeople usually have work clothes. Take supermarkets in RT Mart as an example. All salespeople are uniformly equipped with T-shirt-style work clothes, and different colors are assigned to different positions. For example, the promoters stationed at the signing counter wear white work clothes T-shirts, the tallyman and cashier in the supermarket wear red work clothes T-shirts, and the foreman and account manager also wear white work clothes T-shirts.
