Some excellent responses so far, much appreciated.
Please, keep em coming!
I’ve just remembered one that I did recently.
In summer I was decorating a private school down near a certain Devon seaside town that begins with the letter E.
One of last jobs was to paint a load of banisters on a very grand staircase that had the reception desk underneath.
I covered everything over with sheets etc and asked the receptionist to move to another room for a couple of days.
During the two days I was working on the stairs I became aware that the school was having problems with the phone system and nobody could work out why they weren’t receiving any calls. They had their IT guy looking at it and when he conceded defeat they got a proper engineer in to go through everything.
I saw him at lunchtime and asked him how it was going and he said “I don’t know what’s wrong it. I’ve been through everything and I can’t find any faults anywhere, it’s completely doing my head in.”
In the afternoon I’d finished and was picking the sheets up when I found a phone on the reception desk underneath one of them...
And the receiver had been knocked off the hook...
Checking no-one was looking I carefully put it back on and carried on tidying up with a slight feeling of unease and sure enough about two minutes later I hear the engineer shout “Hey! It’s started working!”
I could hear people asking what had actually been wrong with it and him saying “I don’t know, it’s really weird. It just seems to be working again for some reason.”
I was just getting ready to carry my stuff to the van when he walked past me and I jumped as he said “I didn’t realise there was another phone there” pointing to the one on the desk.
“Ah well, it’s all fine now anyway, I’m off home.”
“Yeah” I said. “You did really well”...
