Many thanks to Mark and Kevin for the kind responses. The toffee crisp guy was a haulage contractor, delivered stuff for Rowntree of York. He had a depot near college (slipper lane?). I think he also levelled the ‘new’ football pitch, the one near the road. Typing this I can taste the round purple ‘tiny’ slabs of meat we got at dinner, the see-through powdered milk and worst of all, the tea, brewed inside the nuns old tights. Only ever drink Nambarrie now. Couldn’t make this stuff up. I should get out more.
