But in the end I walked away.
I had an engineer turn up today to repair a machine that wasn't even broken.
Some idiot couldn't work out how to press the correct button, so an engineer had been called out for a wasted journey.
It was then suggested I spend some time training the person who had the problem.
I tried, I really tried, but unfortunately she is an expert on EVERYTHING, so when I tried to explain, she shouted me down and told me how the machine should work.
It was either that or wring her fucking neck!
