Not the help line
Back in the day (very late'80's early '90's), I was a shift leader running a small shift, max 3, often 2 (including myself) looking after a Mainframe and a number of AS400's.
Our customer helpline was advertised as 24x7 but was actually manned 8-6 and the phones switched over to us after hours, so we had to field helpline calls out of hours when we were pushed to get things like the printing done to make the taxi schedules.
So we fielded calls from our very non-IT aware customers who thought switching the screen off/on restarted the 'computer'.
This one call stood out - it was the wee hours on new years day - yes we worked 24x7x365. - had a phone call asking us to replace a window which a brick had been thrown though. The caller was a bit miffed that we did not drop everything, drive about 150 miles there and then to replace the glass when I explained that we where the computer helpline and not a facilities helpline and to contact his area manager.
It turned out that his area manager had told all his managers to call us for everything instead of calling him for non-IT (buildings etc.) problems. I think he was hoping for a night with no calls about broken windows etc. The building was in one of the rougher parts on Manchester.
Also the number of times we answered the phone to be moaned at for not returning calls when a message was left on the answerphone - there was not an answerphone, there was a message if the phone was not answered in about 30 seconds saying words to the effect "Sorry, we are busy, please ring back later, no messages will be taken".
