'What did I tell you about coming here again?!; You have been banned!': Mousy librarian flips a switch and rebukes a rampaging Karen, telling her off and running her out of the library for good

Bookish kids will always remember the day they got their library card. Perhaps it's because this is the first card you ever authenticate with a signature at the bottom, or perhaps it's because you had unlimited access to all the books in the world and finally had a friendly old lady who was willing to point you towards your next adventure. And everyone knows that friendly librarians are the ultimate pseudo-granny. In this case, one librarian fulfilled her dream grandma destiny when she went into protection-mode to save one of her regular patrons from a rampaging Karen. 

By breaking her sweet, old lady persona, the librarian surprise-attacked the entitled woman who was badgering a studying student, making a scene that would cement into the memories of everyone in the stacks that day. Keep scrolling to read the full story on how the librarian vanquished a woman who was hellbent on forcing a library patron to share writing materials with her kid and how she's likely to never bother someone at the library ever again.
