As promised, here’s a graph of my typical coffee-drinking habits. In July 2015, I drank a total of 95 cups of coffee (wow, that is a LOT), only one of which was bought in a coffee shop.
And here’s the spreadsheet with the results. I assumed a value of £2.20 for a shop-bought coffee, and calculated my ‘potential’ savings (obviously wildly inaccurate, but kinda fun). I mean, sure, if there was a branch of Starbucks in my kitchen, I’d probably go there every morning. But there ain’t, and so probably at least half of my coffees would be instant anyway. But let’s imagine that a multinational corporation has indeed leased a franchise in my flat. I’ve made a saving of £197.40. I’m filthy rich!
