I love going to libraries, but I don't often like the librarians, just the way that they seem to get really annoyed when I ask where something is and I then ask them to be more specific than just "in that room over there".
The privately owned ones aren't so bad although they sometimes charge late fees. It's the public libraries with volunteer staff that get annoying, they get annoyed by me not knowing where a certain section is (as I said above), they have ridiculous outdated policies regarding the computers (anything you save has to be on a floppy disk you bought from them, you have to sign in with your full name and social security card and even write down every site you plan to visit, they have signs all over the place urging everyone to be careful with who they give their "electronic mail" addresses to, as well as to stay away from "extremely dangerous" sites like MySpace).
