In fact, the so-called hidden rules of the industry are only for those who want to get more wealth. Old oil basically has no cost. Someone picked up used gutter oil from others and sold it to merchants at a low price after simple treatment and filtration. There is a big problem in the safety and hygiene of this oil, which is harmful to people's health. However, the comparison between the prices of new oil and old oil has attracted many people with ideas. They go against their conscience and morality and get more wealth from it. Among them, there are also many businesses that insist on making clean and safe food for the health of diners.
As long as we casually search the old oil in hot pot restaurants online, there are countless cases. Seeing these cases, we are all scared. Eating out is a game. If you are not careful, you may eat old oil. In our real life, there are many shops that use old oil. Some storefronts are exquisite, concise and clean from the outside, attracting diners to eat. However, when we went to the kitchen, we saw that it was a mess, with rats and insects breeding and using unclean ingredients. Sometimes when you eat out, you will have diarrhea and upset your stomach the next day. The existence of these situations makes people feel at ease when eating out.
Nowadays, the competition in the catering industry is fierce, and some merchants attract customers with low prices. But if the price is low, the profit margin will be less, and some businesses will start to use old oil, thus increasing the profit margin.
I also call on everyone to choose a familiar and guaranteed storefront when eating out. At the same time, I hope that this bad industry hidden rule can be reduced or even disappeared.
