I think it is reasonable that Haidilao does not allow customers to bring their own ingredients.

First, Haidilao is a business shop after all. It has its own rules and regulations and its own ingredients. If you go out to spend money to eat, I suggest you buy your own ingredients and eat them at home. The reason why Haidilao is expensive is because of their thoughtful service. Maybe you spend money to buy it, but you actually enjoy the environment and service in their store, and eating is supposed to provide ingredients. If you bring food yourself, you lose the meaning of going out to eat.

The second reason is that Haidilao does not allow customers to bring their own ingredients, which I think is reasonable. If everyone goes to eat Haidilao, they have to bring their own ingredients, then Haidilao will become a shop for processing ingredients, instead of providing a place for customers to eat. Haidilao is a complete catering industry serving customers. I think customers bring their own ingredients, or the ingredients of Haidilao, which can't meet the needs and taste of customers. Then my proposal is that Haidilao should be able to accept some suggestions from the public, improve its own ingredients, or provide better services.

Third, eating in Haidilao is quite expensive, and it should also show its high value. Such an expensive sea fishing should not have some customers. This paper puts forward the scheme that the problem has not been solved. Haidilao should pay attention to its own shop ingredients and customers' feelings, and should accept reasonable suggestions and improvements. If Haidilao is very satisfactory to customers, everyone will definitely not bring their own ingredients into the store.
