My school is ruled by cliques. As soon as you walk in you can clearly see the group of jocks, druggies, nerds, popular girls, preppy girls, etc. That being said, everyone gets along pretty well and cliques mix together a lot.
There are coco-cola logos in every hallway and other company logos that sponsor us everywhere else. The only food you can get is from vending machines, but there are a few fast-food places around the school.
Although my school is mostly a sports school (and I am not at all a sports guy) I fit in just fine. I love my fellow art and game geeks.
