I mean, a grande americano at Starbucks here is $5, and supposing your partner or roommate uses it too, and that maybe a third of days you have 2 coffees, that would cost average of $13/day so yeah, you'd make it back in 800/13 = 62 days. But look, if you don't want to drink coffee this often, or are even less precious with how you like your coffee then it may not be worth it, I'm not judging!

And you can eliminate the last 5 minutes of human interaction outside of work that you get in your day! What a win! /s

When buying coffee outside the home, it's also for the change of environment, like renting space at a table in a third space.

I don’t want to pay $5 for the 15 seconds human interaction it takes to make my coffee order and silently pick it up when the very busy barista shouts my name. The 15 seconds are usually pleasant enough, a smile, please, and thank you. But human companionship at the equivalent of $1200/hour is pricey.
