DaisyAnne He had spent his life in racing industry, and enjoyed and occasional bet, but this had stopped because he couldn't afford it, although he still watched all the racing on a small tv that did not even run to a zapper. He saved his AA, bought a new bigger tv with a remote control then he contacted an old friend, who would come round on a Saturday afternoon, take a tenner, put a couple of bets on the afternoon's racing and the two of them would spend the afternoon cheering on their fancy, now he had a tv that gave him and his friend a good sized screen and good eception Again, as you have said, it did his mental health a power of good.
So if this elderly couple, once they get AA want to spend some of it on a gardener, they are free to do so.
