I’ve just remembered that when we had to start keeping an eye on my MIL it was much better to give her a small amount of cash as she kept losing her bank card. She insisted on being able to go to the local Co-op and it was one of her few joys in life so it wouldn’t have worked if we’d done all her shopping for her.
I’m a gardener and when I started, a lot of my income was in cash but as the banks have closed branches and COVID stopping people going out very few pay me in cash now.
