1, the calibration source is fixed.
The school canteen does not need to consider the problem of tourists, because it mainly faces the students of the whole school. When it's time to eat, people have to line up for dinner. That scene is really spectacular. Let's roughly count the number of students. A university has four academic year groups, one academic year group has at least 10 major, and two classes in one major have at least 80 students. Together with the faculty and staff, there are at least 4000 students. If the school is big, it must have ten thousand students. These are his regular customers and will not be lost, because ordinary schools also explicitly prohibit takeout.
2, the cost is low
Compared with hotels outside, the school canteen has no rent. The meals in the canteen are basically big pot dishes and big pot rice, which is not so particular. Take my school as an example. I won't mention the name of my school here. Rice is 20 cents, a vegetarian dish is around 2 yuan, and a meat dish is 3 yuan. -5 yuan, so one meat, one vegetable and two rice is about 6 yuan -8 yuan, and the quantity is still large, so you can definitely eat enough. If you eat in a restaurant outside, a bowl of rice is 2 yuan, and a meal is only a fraction of a dish. The school generally implements the meal card system, that is, the money is charged into the meal card in advance, and then the card is swiped on the card reader when eating.
3. There are subsidies
In addition, school canteens are subsidized by the state. Not for profit, but for serving students well. The hotel outside is different. It belongs to the purpose of investment, management and profit.
There is also a joke about the canteen, which was widely circulated when I was at school. Tell everyone: when I was a freshman, I would scream when I met a creature when I was eating in the cafeteria; When I was a sophomore, when I met a creature in the canteen, I would silently dump the food. When I was a junior, I met creatures in the canteen, and I would use chopsticks to clip them out and put them aside. When I was in the third year of high school, I met creatures in the canteen and ate them directly as meat dishes.
