During the time I ran my own business I encountered a few of those “awkward” ones….
We had a policy of checking mains plugs and leads on customers repairs for wrong fuses and unsafe Joins etc. Any that were found were put right free of charge and the customer informed when the repair was collected.
One set, a Thorn 9000 had one of the most unsafe mains leads I had ever seen. The original lead had been cut and extended with a length of white doorbell wire. There were two bits of chock block with bare wires poking out and from one of those there was another pair of wires going to a male two pin plug!
I removed the lot and fitted a new mains lead to the set of the same length as the bodged cable had been. In retrospect maybe I should have rang the customer first. When he came to collect the set he asked what the bag was on top, I explained it was his old lead and that I had fitted a new one as that one was very dangerous. He went berserk! ” What! I plug my table lamp into that! put it back!”. I politely refused trying to explain that I would probably be responsible if someone was injured or worse!
What happened next surprised me a bit. He pushed the set over onto it’s screen, wrapped the lead around his hand and wrenched the lead (complete with flex grip and on/off switch) from the set! He threw the new lead on the floor, shouted some more abuse, picked up his set and stormed out! Luckily he had paid the bill before he saw the carrier bag and lost the plot!
