Just seen it on the news - Smithfield Market..
Our neighbour, Henry T, had a butcher's shop in Leeds market. On Saturdays he did 'pick a bag' deals around closing time. They were laid out on a table in front of the shop and you took a chance - sausages, mince, stewing steak, it was all there. He would then hawk any left over bags round the streets for a few bob a bag. He always had a 'special' one for mum because of my brother who was disabled.
Happy days.
