As regards Butchers....worked for one after school at nights and got 12 bob. The day after leaving school went full time at 37/6d. There was no waste then in a butcher shop, all the fat cut off meat went into the vat and other things beside and was the source of your dripping. There were sausages and sausages the best customers got the best sausages. The bones were sold for making soup. If he could have found a source for the blood scrubbed off the chopping blocks would have sold that, maybe it went into the Black Pudding which would have been going too far after being scrubbed of benches with wire brushes into a pail of water. Nowadays if could find a good butcher would stick with him rather than the frozen packaged meats sold in supermarkets. JS
