I don't think many (if any) ordinary folk had current bank accounts as we know them today, let alone joint accounts. The system in National Service days was that a serviceman was paid weekly in cash at a pay parade. If (as was common) he had allotted part of his pay to someone at home (eg wife or mother) that person had a book of dated authorisations and collected the cash weekly from a post office. I guess that similar arrangements had existed from time immemorial. I suppose that in the trenches of WW1 the men were paid as and when, probably when they were back in rest areas. (After all, there weren't many NAAFI's on the Front Line to buy stuff in!) But the person at home was still paid regularly, as above. Someone more knowledgeable will correct me if I am wrong! AF
