I spent most of today working on the next 100 Proofs that the Earth is a Globe, which I posted a while ago. It’s about heat.
It wasn’t actually a very hot day today – today’s post title was really about completing that article. Still, I stayed inside mostly, because there was a hint of smoke in the air still from the bushfires. The weather bureau reckons this will hang around Sydney for weeks.
Early this morning I did make a trek to the supermarket to get some groceries. My wife drinks coffee – I don’t. She had coffee on the shopping list. I know the type she likes is “Medium roast, Strength 5”.
Looking at the shelves, I saw that a jar of that was $9. But right next it was the same brand, “Dark roast, Strength 8”, on sale for $6 for the same sized jar. There was no sale sticker on the Medium roast.
So I thought: if I get the Strength 8 stuff, and water it down an extra 37.5%, that’d be the same as Strength 5, right? And because it’s more watered down, I’d be using 37.5% less of it, so we’d be saving that as well. Which makes the effective price only $3.75 for the same size jar as the $9 medium roast. And if I buy a dozen jars of the Dark roast, we save a whopping $63 !
I’m sure that all the coffee drinkers out there would find this eminently satisfactory, yes?
However, I bought the $9 jar of Medium roast, because I know my wife. I told her the story, and she said she wouldn’t have minded if I got the Dark roast! 🙄
