Principle of self-selected weighing fast food

Merchants use electronic scales and other tools to provide a weighing service for each customer when selling food. Customers select their favorite ingredients and then place them on the designated weighing platform for weighing, and when the weighing is complete, they go to the cashier's counter to pay for the ingredients they have selected and can pick them up. In this way, merchants allow customers to choose their own food, weigh and pay for it, avoiding the problem of waiting in line and wasting time, while also reducing the risk of manual calculations and shortages.

The advantage of self-selecting and weighing fast food is that customers can independently choose their favorite food, avoiding the trouble of waiting in line and wasting time, as well as reducing the risk of manual calculation and shortage of catty. In addition, merchants can more accurately understand the needs and preferences of customers, improving sales efficiency and customer satisfaction.
