In the days before the council introduced “wet money”, a couple of extra quid a month to work in all weathers, the rule was you didn’t work in the rain (“It’s a health and safety issue, ain’t it guv”). So at the first sign of grey clouds or even someone walking past in a raincoat, we would stop what we were doing, look up to the sky and put our hands out to see if we could feel rain and if we did, would make our way up to the shed for a few hours of tea drinking.
The hard and fast rule was if three cars passed consecutively with their windscreen wipers on, it was officially raining so we could stop work. How mad is that?
