I remember buying Hypo crystal's in large tins and using it for everything, just mixing it for films and paper, didn't use stop bath, just water, although if we had some around I would mix some clear viniger with the water, worked well, I would use the hypo mix for films untill it stopped working, ( pen the tank an check, if after a few minutes the film hadn't cleared just mix a bit more and re fix) also for paper, 2 or 3 sessions and throw it away and smix fresh, again a rinse in some water between develop and fix, always worked and I still have one or 2 prints from those days and still looking good after 60 or so years, maybe that's why some people think I am a little careless these days, but in the good old days it was just the way we did things, these days it is a lot easier and I would not go back to the old days, give me fast fixers and proper stop bath for printing any day, I also remember when in a hurry I didn't bother with the watert or vineger stop, just poured the developer out and fixer straight in, never seemed to make any difference to the film, just made the fixer's life shorter, I sometimes do the same thing today, still doesn't seem to make a difference,
