The crayfish project in the foot bath shop refers to the project that provides crayfish food service in the foot bath shop. In order to expand business and increase revenue, foot bath shops began to provide crayfish food services, which became a relatively popular business model. The specific operation method is that foot bath shops set up crayfish stalls inside or outside the store to provide crayfish and other late-night snacks to attract consumers to come and taste them. The advantage of this business model is that it can use the free time and space of the foot bath shop to save costs, while attracting more consumers and increasing profits.
