Did I mention the numnutz who filled a 5000 gallon tanker with araldite and then sent it off to somewhere in the north. As it drove away a thick stream of glue reminded him that he should have checked that the outflow valve was closed...
No mobile phones in those days. We often wondered what the truckie's face was like when he tried to make his delivery and found the tank was empty! Or the people who were driving behind him on the motorway - but this was 1965/66 so not so much traffic!
