Don't know, but I just remembered a mutual joke from the 80s
Someone at work asked if I'd got my new haircut on the NHS, and I replied that by coincidence it was the same price as a prescription charge.
I've cut my own hair since 1989. Away from home in Austria, one evening I looked in the mirror, thought how difficult can it be, and got going ...
Next breakfast and the next couple of days 5 people asked me whereabouts on site the hairdresser was, so it couldn't have been that bad.
