Back in the day when I was a "Storeman" at an Electronics shop,we got some special 67.5v batteries in.
They were used in some sort of gear used by a Govt.Department.
This customer (& a few others) used a fair number of them,so the Boss decided to keep them in stock.
The more common version was a small rectangular unit,but these looked like a very large version of modern 9v batteries,complete with "press stud" connectors on one end.
The proportions were different,though,as they just fitted into the stock shelves.
As the shelves were metal,we put them with the "press studs" facing outward.
All was well,until one sweaty Summer day,when a colleague asked me about something on an Order Sheet.
Leaning against the shelves (as you do!
),I placed my arm across about four of these batteries.
Ouchhh!I was quite surprised by this and yelled "Golly Gosh,Gee Whiz!" or something of that nature.
Luckily the Boss was elsewhere,so I didn't get chewed out for swearing just outside the Office.
