Fortunately time has dulled my memory, but incidents of numpties loudly complaining about something which was demonstrably down to them were frequent – maybe two or three a week when I was in a retail model shop and in kit manufacturing.
I'm on record as having quantified the percentage of "faulty" electronics sent back for repair or replacement – and which were either not faulty or had been obviously connected without reference to the instructions – as at least 80%. I still get them.
The next favourite down the list was kit parts which "didn't fit" – generally because it wasn't the part which was intended for that purpose, or the builder had jumped the gun and fitted something else prematurely which was now in the way.
Lawrie White (Model Slipway) tells the story of a customer who telephoned to ask if it would be 'all right' to paint his Maggie M a different colour to the one on the box lid.
Ron Dean was made to regret writing "cement the ballast weight into the bottom of the hull" in an instruction manual when a customer took him exactly at his word and used some of Blue Circle's finest. He was apparently puzzled as to why the model refused to float.
My own particular favourite was the bloke who came into Pegasus toy and model shop in Nottingham on the day after Boxing Day and slammed a 4.5v dry battery down on the counter. He said that he'd brought it back to complain that it had gone flat. It turned out that his kids had spent most of Christmas Day and Boxing Day playing a game which flashed about a dozen bulbs when a correct answer was given. Nevertheless "what was I going to do about it?" I think I just stared dumbstruck at him until he left…………….
One tries one's very best to make allowances but there are still those folk who would best serve humanity by not breeding.
