I commented a few weeks ago about a large country house where back in the 1970's a lady who was a director of a major company lived in the summer house, her cousin who lived in the big house was a very resourceful lady.
She had bought a lorry load of carrots as stock feed for her cattle which had been coated with purple dye immediately before delivery, she had the petrol driven bale elevator laid out flat with the two farm labourers using a pressure washer to wash the carrots and re-bagging them ready to take to a local produce sale with the intention of more than doubling her money, I doubt any of them knew what a RCD is.
