This article frames the cup-of-coffee pricing comparison as: "$100/mo is less than a cup of coffee every day". But I most frequently see the comparison as: "$5/mo means giving up just a cup of coffee once a month".

I like coffee, but I've not bought even a 4€ cup of coffee in a few months. Actually I don't visit coffee shops a lot, I much prefer drink my coffee at home (or at work, where it's free)...
