A couple of my youngish neighbours (a Russian and an American as it happens) wanted to visit a few traditional pubs, so off we set to London. As one of the pubs I planned to take them to was The Nag's Head in Kinnerton St I had the foresight before we went in to ask if either of them had any cash, as I speculated that it was the sort of pub where they might not have the equipment to process a card payment. I didn't know for sure as I had obviously never tried to use a card in there. It transpired that neither of them had a penny on them, and as we couldn't find a cashpoint in Belgravia we had to find a shop where they could buy something so that they could get something called "cashback". This seemed to work to their satisfaction using something called "contactless", whereupon they discarded the bits of paper they were given, presumably trusting the bank to get it all right. They didn't strike me as the sort of people who would check their bank statements anyway. I now realise that I live in a different world to most people, but I think I'll stay in it for as long as I can.
