Many years ago someone I know well worked in a village shop, on the butchery counter. Mrs Smith comes in, wanting some corned beef. My friend reaches for the corned beef on display to slice it for her but she doesn’t want that piece, she wants some from a new tin. Sigh.
So- the customer is always correct remember- he nips out to the cold store and retrieves a can of corned beef (BTW- these things are big, about the size of a 5 litre oil can). Can is opened in the preparation area to the incessant nagging of the customer. Using an old fashioned ‘stab it and jack it along’ type can opener can leave nasty sharp edges and inevitably under stress the web between my friend’s thumb and fore-finger was sliced open. Loads of blood, all over the place. Woman rants and nags on, oblivious of the damage. Under the tap goes the corned beef. A quick nod to the other staff to continue serving and the meat was sliced to Mrs Smith’s satisfaction.
The customer is always correct.
Caveat emptor.
I do not condone this behaviour. FWIW, It was in about 1980 or 1981.
