What people in Queensland, Australia call a canteen. The term is also used officially by the schools.

I couldn’t care less (but one must keep up appearances, right?)

The most holy place in the school area, or maybe even the state itself. It is where people go at lunch to buy and eat their sacred meals and share with their mates. Unfortunately, it is also where some mates will commit the crime of {dogging the boys} and not buy each other food.
