@Fullycaffeinated @HebrideanHecate @Ladyfat These days there are a few things that she physically can’t do with cash or a cheque any more, so Mr’s nephew does it online with his card and she then gives him cash.
The only actual day-to-day cash I use is when I buy her something from the shops and she gives me cash back, which I then use for either sewing group subs or, if it’s building up in my purse, a bottle of wine and other bits from the cafe mid-shopping-week.
