How does the school cafeteria order the number of meals for each meal? Whether it's based on the number of students or a weekly average, there will always be some students who don't eat, bring their own, go out to eat, and eat a lot of food .....
Secondly, the scale and efficiency of the kitchen is the workload of supplying food to hundreds of people is not something that can be done by an ordinary person. The more people you supply, the larger the scale of the kitchen you need.
If the equipment and quality of the staff can't keep up with the efficiency of the kitchen, then you can only imagine what the food will be like. Nowadays, people are very picky about their food, and if they are not satisfied with the food, they will complain a lot. If you're not satisfied, there will be a lot of complaints and protests, and a lot of school cafeterias that are dominated by one person die in this regard.
