Out of office emergency phone number

Walking to work today I noticed a sign that read, 'Out of office emergency telephone number'. Now this is generally a good thing. I walk past the GP so a number there would be helpful. But this notice was on the local library. Why would anyone have the need to call the 'local'* library outside of normal library times with an emergency?

'Please, I need to know, is that Stephen King novel in yet?'

'Do you have any red recycling sacks I can come and collect when you are open?'

'Could you look up onomatopoeia in the Ecyclopedia Britannica for me?'




*This isn't a major library but a local sub-branch.
