This is everyone's consumption concept is different. First of all, in the canteen school, everyone has to go to the canteen to eat, and there is no other choice. Moreover, the school canteen will not cook according to the requirements of each student. So I will spend dozens of dollars to eat, and I feel that I have spent a lot of money. When eating out, you can order according to your favorite food. And the most important thing is that you can do what you like while eating. If the restaurant is not well run, we can also complain to him. But it's no use complaining about your food in the school cafeteria. Therefore, it will cause an imbalance in consumer psychology.
