At my school everybody liked the janitors. We always went out to see them in our lunchbreaks (they also gave us cigarettes when we didn't have any, so that was a nice extra). Everybody threw away their stuff, and when you didn't they just walked up you and said you had to pick your stuff up and throw it away. Might seem strange, but we actually looked up to our janitors. :P Everybody talked with the Lunch ladies as well. Well, not everbody, but a lot of people did. And everybody treated them friendly.
