CLARIFICATION: Just so it’s clear, this question is specifically about the economic claims made by the meme presented below. It is a NOT question concerning the origins and etymology of the word “shot” in any way/shape/form. If there is a desire to discuss/debate the etymology of the word “shot” I have started a thread at the English Language SE site specifically for that purpose.
This image is popping up on my social media feeds, and I wonder if there is any truth to the presented claim. The text reads:
‘A SHOT OF WHISKEY’
In the old west a .45 cartridge for a six-gun cost 12 cents, so did a glass of whiskey. If a cowhand was low on cash he would often give the bartender a cartridge in exchange for a drink. This became known as a “shot” of whiskey.
That little bit of trivia seems a bit too perfect: Guns, booze and the cost of one thing connected to one thing is the same as another thing. Perhaps this is a “legend” that spawned from people trading physical objects instead of using cash at local stores and then was distilled (figuratively) into this one sentence over time?
