From the age of 13 I worked Saturdays in my grandfather's butcher's shop and also during the Christmas school holidays to cope with the pre-Christmas rush.
As well as serving customers, taking payment and giving change, I kept the shelves stacked with 'accompaniments': mint sauce, stock cubes, horseradish, etc, etc; took down orders over the phone; did occasional home deliveries on a big old bicycle with a basket on the front and the shop name on a plate attached to the frame; learned to make sausages and just generally acted as gofer. I had to help scrub out at the end of the day with lots of boiling water and carbolic soap - I can smell the soap now, just thinking about it!
The shop was always perishing cold except for about a month in the height of summer and I must have looked like Nanook of the North with all my layers of clothing under my overall, plus 2 pairs of socks, tights and fur-lined boots.
I loved that job, despite the cold and the carbolic - chatting to customers when it was quiet, the cameraderie with the Saturday boys and working for grandad - a firm but fair boss who expected a day's work for a day's pay and certainly didn't cut me any slack just because I was a relative.
The job ended when my grandad retired a couple of months before I left school and the butcher who bought the business had his own family on hand to assist him.
Oddly enough, I was only talking to someone recently about that job and about how much I'd learned without being aware of it until years later about how to buy and cook meat; what cuts are best used for which dishes and so on.
I still enjoy a visit to a good old-fashioned butcher's shop.
