When farmers sell grain, why do some people say that scales, electronic scales, and floor scales are not safe?

The reason the scale is unsafe is that the right hand has a rotatable iron rod that can add and subtract weight. The reason why the scale is unsafe is that I heard from others that there is a remote control that can control addition and subtraction, and the large scale can also be controlled manually.

Let's talk about something true that my assistant learned not too long ago. An uncle of my neighbor planted 6 acres of corn this year. The yield is not bad. He has his own scale, which totals about 6,500 kilograms. Before planting wheat, he wanted to sell the corn to buy seeds, fertilizer, land preparation and other expenses, so he loaded it on a truck and took it to a grain distribution center to sell it.

Not far from our village, there are two grain distribution centers, one in the east and the other in the west. They are not very big, but most villagers will choose to sell here. The price in the East is 0.93 yuan/kg, while the price in the West is 0.94 yuan/kg, which is 1% higher per kilogram. This uncle plans to sell it in the West. At the end of the day, many of the grain sellers lined up for about an hour to get weighed (they were all in bags and using weighing scales, not large scales). After weighing, the total weight was only 6,030 kilograms, nearly 500 kilograms less than their weight at home. If the difference is about 50kg before and after, this is still normal, but now it is 500kg less. The uncle thought there must be something wrong with the weighing system and asked for a new weighing. However, people disagree about the weighing system. They want to sell it, but they don’t want to sell it. Not very friendly. The uncle took it to the east.

There are also many people in the east room. They lined up for a while and started weighing. The final weight was 6480 pounds. They sold it to the house. A simple calculation shows that according to the Western weight and price, it can be sold for 5668.2 yuan, while according to the Eastern calculation, it can be sold for 6026.4 yuan, a difference of 358.2 yuan, which is already a considerable sum for farmers. . As can be seen from the above, there is no problem whether it is an electronic scale, electronic scale or floor scale. The problem is "heart". As the last friend in the chat said, no scale is accurate when one's conscience is broken. Others suggested that when selling grains, they should be weighed at home and sold if there was not much of a difference. Some friends will say that this is too much trouble, so one should have a rough mental weight. If the difference is too big, don't sell it, especially if the purchase price is much higher than the local price, one should be more considerate.
