Eating three meals a day does not mean eating out three meals a day. For most families, breakfast and dinner are usually eaten at home, and may eat a meal outside at noon. The reason is that eating out, first of all, food safety and hygiene cannot be guaranteed. Secondly, eating outside will also be a waste of money. So it is normal for a restaurant to lose money. There are some catering outlets that make good meals and there will be a lot of consumers. But some restaurants will be second best, in which case customers may eat only once and not go back a second time.
I prefer to go to the market to buy food after work and cook at home. Because the oil in my own home is safe, it may be better for my health. Of course, sometimes when I'm busy at work, I'll eat out or order takeout, but I've always found takeout to be a bit of a pain in the ass. But for a long time you will always feel that the takeaway is especially greasy and your stomach will feel uncomfortable. Sometimes when you order takeout, you will have diarrhea. I think that some restaurants outside are usually semi-finished products, directly fried and can be eaten. And half-cooked products for the stomach and intestines may have a greater impact, a long time, may intestines inside the oil will be more and more. Even the phenomenon of a big belly will appear, so if there are no special circumstances, I will not eat outside.
There are times when a restaurant loses money and has a relationship with itself. I remember once it was reported on the internet that a delivery man reported the restaurant where he delivered his food. It was because he saw a dirty and messy scene in the back kitchen and the oil and materials used were not hygienic. After he reported the restaurant, the family restaurant was also closed. So even though a lot of people eat three meals a day, they don't necessarily eat out very often. That's a big reason why so many restaurants go out of business.
I think most people still rely more on eating out. But they will prefer to eat at food establishments that are relatively safe in terms of hygiene. They will also pay more attention to the taste, and if the taste is not good, they may not go back a second time. This is also the reason why some restaurants will close down very quickly.
