Well I do have old fashioned housekeeping money.
My husband puts a hundred quid in my purse on a Friday , it's not really enough to feed us, three huge dogs, buy our wine and cider, etc....but somehow we do manage. We eat three excellent meals a day, cooked from scratch, the dogs are in superb condition, and we get a glass of wine or cider with our evening meal. We cannot afford to go out, or eat out, and sometimes, well almost always, I only have a tenner left on a Monday morning. Having a set amount of money in cash concentrates the mind and nothing is wasted.
