My father was always sort of trying to make an extra few bob when he wasn't working and we were always shooting in black and white in those days, and he would never throw away the short ends because, you know, 15ft or 20ft would make up several cassettes for still photographers, and so he'd keep all his short ends and then go into the changing bag and he'd wind on these 5ft lengths of cassettes and feed them into the... into the cassette, and then take them up to a shop in High Holborn called Brunnings, which was... was a shop that sold still cameras and movie camera accessories, and lenses and so on, and, of course, he made quite a bit of money out of this because the film was so scarce, the only disadvantage was it didn't have the edge numbers that a... a proper cassette would have, but that was a little sideline that sort of kept things going when he wasn't working.
