By your description of this woman's behaviour it sounds like she might be slightly mentally disturbed. "Normal" people don't angrily tell people to move just out of the blue in the way you described.
Seems like the librarian started out handling the issue a little wrong. But it also sounds like she came around pretty quickly.
