Why should cafeteria food be cheap?

* Economies of scale. Cafeterias serve a large number of people, which allows them to purchase food in bulk and negotiate lower prices with suppliers.

* Limited menu options. Cafeterias typically offer a limited menu of items, which reduces the cost of food preparation.

* Subsidized prices. Some cafeterias, especially those in schools and hospitals, are subsidized by the government or other organizations, which helps to keep prices down.

* Lower labor costs. Cafeterias often use part-time or low-wage workers, which helps to keep labor costs down.

Of course, not all cafeteria food is cheap. Some cafeterias, especially those in high-end restaurants or hotels, can be quite expensive. However, in general, cafeteria food is a relatively inexpensive option for people who are looking for a quick and easy meal.
