Checked out a study room, before realizing I wasn't trusted to get food on campus after doing so. Upon my return I am told that my privilege of studying in private had been revoked because I returned the key in "an aggressive manner". I tossed the key onto the counter from two feet away.
This happened four years ago and I still find myself haunted by the experience. It's absolutely deplorable to me that a librarian would think to take away the ability to work in peace as a means of imparting some lesson. The library is supposed to be a place of academic refuge. That someone whose position is to help others would be willing to hurt me so purposefully is heart wrenching.

Other than this experience, the library was very accommodating.
