The rule that Haidilao does not allow customers to bring their own ingredients is reasonable to some extent. Haidilao is a restaurant that provides hot pot service. Its purpose is to provide high-quality ingredients that meet the standards and ensure high standards of food safety and hygiene. If customers bring their own ingredients, Haidilao cannot guarantee that these ingredients meet the standards, which may affect the dining experience and health and safety of other customers.

In addition, Haidilao has strict standards and procedures in the selection and supply of ingredients, including cooperation with suppliers, inspection of ingredients and quality assurance. If customers are allowed to bring their own ingredients, it will bring challenges to the food management and supply chain of Haidilao, which may affect its quality and reputation.

However, some customers may need to bring their own ingredients because of food preferences, health needs or religious beliefs. In these cases, Haidilao can consider providing some reasonable solutions on the premise of ensuring food safety and hygiene. For example, customers can be allowed to bring some special condiments or seasonings, or provide additional pot bottom options to meet the special needs of customers.
