Can chefs in public institutions buy food by themselves?

Chefs in public institutions are not allowed to buy food by themselves. Chefs in canteens of public institutions are not allowed to buy food by themselves, because public institutions have their own procurement system, which requires the use of ingredients supplied by unified suppliers to ensure the quality and safety of food and certain standards. Dining room chefs need to purchase raw materials in designated procurement channels. If they buy or use unauthorized ingredients privately, it will violate the canteen management system and even bring security risks. Institutions refer to management organizations voluntarily established by the government or the public, with the main purpose of serving the public, and authorized by the state to conduct independent accounting, including government agencies, public hospitals, public schools, cultural, sports and environmental protection institutions.
