My uncle had just finished his apprenticeship as an electrician and as a qualified spark, he was taken on by the company who'd sponsored him while doing it. It was his first night shift on his own and he was called out to a pub on Scotland Road, L'pool coming up to midnight. The light fitting over the stairwell had been pulled out and he could see it had suffered some abuse in the past. Determined this wouldn't happen again, as well as sorting out the electrics before putting the power back on, he fixed the ceiling holding the light fitting with plaster and made it look presentable as well as secure. Job done so he was very happy.
He went back to the office and spent an uneventful rest of the night before going home at 6am feeling happy his first day had gone so well.
The following week he was back on days and on entering the office on Monday morning, he was met with some frowning colleagues and asked to go and see the manager. With some trepidation, he went in to see him wondering what it was he'd done so badly.
"Did you fix the light fitting in the ...... pub on Scotty Road?" "Yes I did and I think I did a good job securing it too." he responded. "You bloody idiot, the pub manager's hanged himself only this time, it worked and he's dead!"
A tacit agreement amongst his colleagues was to just repair the wiring when they were called out to this pub and leave the light cable loose as the pub manager would get drunk while serving on a Saturday night, get morose and threaten to hang himself which he often did only for the light fitting to collapse unable to bear his weight. They all knew this was a regular thing so played along with him and his 'suicide' act and he'd come to, full of remorse and promising not to do it again but everyone was in on this and their agreement made sure he stayed undead. Well, nobody had bothered to tell the new lad and let him in on their agreement! This always bothered him no matter how much you reassured him and told, "It wasn't your fault." which of course it wasn't and the firm kept him on anyway where he stayed for over 20 years.
