On the dangers of becoming a cashless society.
Like most people I pay for virtually everything by card these days. But this afternoon whilst shopping in my local greengrocer, they announced that they could only take cash because something had happened to their card reader. Even worse, one of their electric tills wouldn't open either.
The only cash I had on me was £10, and I knew my shopping could be more than that. No matter, they added it all up to a figure of £10.67; I went to the cash point 10 yards away and drew out another £20 - two £10 notes. However when | went back to pay, they had run out of loose change, because only one till was operational. I've been shopping there for ages: they know me, and said to pay the extra 67p when I had it.
I made me wonder what would happen when all the clearing banks close, the cash points dissappear, and everything is done online. Technical faliure this afternoon was an inconvenience, but at least I could still use cash.
