Exactly what I don't need on the last day before my first final. I checked out a tape of a class yesterday to watch on-site. I returned to the desk, but the desk attendant had stepped out. I waited patiently. One of the reference librarians noticed and came over to ask what was going on. I told her I was returning the tape. She told me to just leave it on the desk and she'd make sure the counter attendant checked it in when he returned.
I just got an e-mail telling me that my tape is now 24 hours overdue, and since it's on course reserve that means a $1/hour fine. Now I have to go in to the library and sort this out, when I had been planning on staying inside and studying all day. Blar.
UPDATE: Alright, it's resolved. They actually had the tape and had put it on the shelf, but hadn't checked it back in properly. Annoying, insofar as it was their fault, but also a relief, insofar as I would probably be in a lot of trouble if someone had walked by yesterday and snagged the tape off the circulation desk.
