Oh, don't remind me please, Tony!
I once called into a local hairdressers that was nominally 'unisex' (although I'm sure that they hardly ever got many guys in there), simply because it was late on a Saturday afternoon and the only barber's shop in our small town had already closed. Asking if they could fit me win, without an appointment, for a quick trim, the only woman who was working on a lady's hair turned to the girl on the reception desk and said "You can do that, can't you?"
Not long after she'd got started, she managed to cut my left ear. She was really apologetic, saying "I'm ever so sorry, I've never done that before". Two minutes later she managed to cut my right ear as well!
Throughout the whole of the haircut (or should that be 'earcut'?) I was wondering where I'd seen her before. It was only when she served me in the local Co-op on Monday that I realised that she wasn't a hairdresser at all but just a shopworker who happened to be a friend of the real hairdresser!
