When I was junior school age, from about aged 7 onwards, I got 2/6 (half a crown) on Saturdays. It was spent at Saturday morning cinema, sweets and maybe a comic.
I got a Saturday job when I was at senior school it was quite easy to work from early teens. Mine was in a grocery shop up my road. I did save money then, I coveted a very expensive pair of boots that seemed way beyond my reach, but I did get there in the end, even if it took quite a while. A lot of my Saturday earnings went on Mary Quant make up, magazines such as Rave , Petticoat and NME and going out with my friends if I remember rightly.
