Today I ate lunch in one of the student canteens not the teacher's area.  There were about 700 students eating at the same time.  All 2200 students eat at once on one of the three floors of a huge building.  The food is set out in huge pans and the students serve themselves.  It runs like a machine and is louder than almost anything I can compare at our school.  But everyone takes it in stride.  Today is hot so they all wanted to eat quickly and get out to play before nap time at noon.  Very interesting lunch!  See picture below.
