[The patron] called and said he was always late for work because his alarm clock was going off at the wrong time, and wanted to know if we could help. I thought it might have been set for six o'clock PM instead of AM, but he didn't know how to check. Since it was battery operated, he just brought it in. It was set to PM, so I changed it to AM for him.
And there you go - talk about providing the services our patrons need.
