I had one some years ago; I was offered a choice of "operatives" but bot knowing who was who, I asked for a "nice gentle female". A foolish choice. I got he local Registrar-ess who was embarking on her holidays immediately afterwards; she was attired in an immaculate red trouser suit and wasn't hanging about.
Thought I detected wry smile on her face as she rammed the device home . . . . .the boot on the other foot; payback time; call it what you will. Women too, can have a sardonic sense of humour no doubt detected by every woman in the place. Well, one actually.
She wasn't able to give the all-clear, so a guy did the same job on another day.
Never felt a thing. And I'm still here . . .
