Apparently I missed all the fun at the library today. Some patron went nuts and cursed "Derek" out while he was on the Adult Reference Desk.
As soon as I found out I texted him and asked him what he did to prompt such a response from a middle aged white woman. He claims he didn't do anything but try to help her -- I don't believe him because he can be kind of an ass sometimes. I'll have to investigate some more and find out what actually happened.
