Supervisor: Did you see the email about how patrons need to add their PIN numbers when they’re doing self-checkout?
Me: Yes
Supervisor: Ok
Patron: Hi! I put a book on hold and your system seems to be having trouble finding it.
Me: Can I see your library card?
Supervisor: It’s not working because they have to put in their PIN number.
Me: This isn’t related to self-checkout. Looks like we have only one copy of this title in the whole system, and it’s missing.
Supervisor: PIN number.
Patron: Damn.
Me: I’d suggest going to the librarian over there to submit an interlibrary loan request.
Supervisor: Matt tell them about the PIN number thing
Me: we’re talkinG ABOUT SOMETHING ELSE
