Occasionally you may need to eat lunch in your office. Close your door so the smell doesn't choke everyone in the library. And PLEASE... take your leftovers, food wrappers, and other smelly trash to an outdoor trash can. There is no reason anyone else in the library should have to smell your microwavable corndogs, Lean Cuisine linguine, or leftover fried fish.
And don't pop microwave popcorn unless you make enough for everyone. Mmm, popcorn smells so good.
