I was the Saturday Librarian (yes, it has its own hashtag) at Small Town Library today.
First, a woman was massively rude about a book she requested that was sent to a branch other than what she wanted (investigation revealed that, surprise, surprise, the problem was user error, but she still wrote a nasty note to our supervisor). She was so rude that our normally-very-nice circ lieutenant said after she left: "Good thing the thing she was waiting for was a book and not, you know, a kidney."
Also today, I approved a purchase order for $6,000 worth of magazines. That's about how much money I have in my savings account. Between that and being the sole representative of my department in the building today, I'm positively drunk with power.
