1. The method of selling the whole market. The vendor intentionally does not place the weighing pan on the scale. When the customer is shopping, after pressing the unit price, the weighing pan with the product is placed on the scale, and the weight of the weighing pan is also included in the weight of the product. Within the payment.

2. Impact barrier method. When empty scales, the goods are heavily thrown into the weighing pan. The impact force causes the weight value displayed by the scale to be artificially increased in an instant. When the customer still has to look at it in the future, the trader has picked up the goods quickly and immediately. Report the bid.

3. Keep the base method. When empty scales, the subtitles should all be zero, but some vendors store a certain number of bases in the number of weights displayed on the desktop. When customers shop, they will not be cleared. The base number stored first will be counted together with the purchased items. The payment.

So go buy fish, buy meat, buy fruit in the future... As long as you use this electronic scale, you have to look carefully.
