When I think back however there was some dangerous stuff lurking on the shelves of the corner shop when you think of Cowan’s Highland toffee (with the cow on the wrapper).
And, when you were well financed, the same product - only chocolate coated. 
Indeed Zulu, and I answered HC's post before seeing yours, and I think it is all very relevant. When you think though that many houses of at least my early childhood had lead water pipes, and we were encouraged to let the water run when first using the tap in the morning, or after any lengthy period of non-use!
Things have to change I suppose, and to keep on the subject of Skruntie's thread, yes decimalisation was a wonderful commercial exercise of much worth to us in the retail trade in 1971, but the change was necessary to simplify the process of calculation when buying and selling goods across the international financial world and our customers. Believe me, for staff like me at the time, a stock valuer, it was a tremendous help to use a fully decimalised system

It was just a shame we stuck to an imperial packaging system of dozens, grosses, etc!
