What are the current standard sizes for making cashier counters?

The height of the checkout counter should be moderate. If it is too high, it will make people feel excluded, and if it is too low, it will make people feel unsafe. The appropriate height is between 110 and 120 centimeters, or 107, 108, 126 cm. Electrical appliances such as electric stoves and coffee pots are not allowed in the cashier counter, as this can easily lead to disasters and verbal abuse. Faucets and flushing sinks are not allowed next to the cashier at the entrance. The safe where money is placed should be private and cannot be seen by others, but cash registers with small amounts are not restricted. Feng Shui perspective: (Those who don’t believe in Feng Shui can ignore it.) The cashier should be set up in an arc shape, which can form a "jade belt wrapped around the waist" layout, which is conducive to gathering wealth. The height of the cashier should also be moderate. A cashier that is too high will cause It has a feeling of being excluded from the outside and is convenient for checkout. If it is too low, wealth will leak out. The appropriate height can be between 110-120 cm, or use the "Luban ruler" height: 107, 108 or 126 cm. How much space is suitable for a cashier counter? Take a bookstore as an example. My experience is: for bookstores within 100 square meters, the cashier area should be controlled at 1.5-2 square meters; for bookstores over 100 square meters, the check-out area should be around 2-3 square meters. If it exceeds 500㎡, two cash registers must be activated, so the location of the cashier will naturally be larger, but it is best not to exceed 6㎡. In supermarkets, the products selected by customers are often rich in content and relatively large in size. In order to allow customers to clearly see the entire pricing and payment process, the height of the checkout counter should not exceed 0.7 meters. Moreover, supermarkets complain about low prices and low checkout counters. Putting goods on the shelves can give customers a cheap psychological feeling.
