I think there has to be an opportunity cost for everything, and coffee shop outings should be considered the same. If you're gonna go for regular coffee, then you have to cut back on some other expenses. Whether it be cosmetics, a cheaper brand of another good or something.
I also think that if you take the time to go out to a coffee shop, having the ability to write a decent post on Hive about the experience is a great way to subsidise the expense😉
