The price of food is the most sensitive thing. Each student compares the price of each dish in each restaurant to choose the most suitable meal. Although everyone wants to reduce food prices, it is all kinds of factors that make it sleepy. The factors that students consider when dining most contemporary college students are only children. The economic development in different regions is unbalanced, the family economic conditions are different, and the dining factors are obviously different. Most students finally choose to eat in the school canteen, because the price of food is lower than that of the canteen outside. Although college students have consumption psychology in one way or another, in the final analysis, they should be based on economy. College students have limited spending power and mainly rely on their families to provide financial support. In the contemporary school catering service, the price of food and vegetables still plays an extremely important role. Secondly, because of the heavy study tasks or tight courses on weekdays, the geographical advantages of the school canteen make most students eat in the canteen. School canteens should also pay attention to humanized service and family-style service, so that students can have a safe meal far from home. What students feel when they eat is natural, nutritious and hygienic food, which is also the internal improvement of canteen staff.
