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)...
Also if they argued that 7€ would be just 2 beers per month... maybe I'd still take 2 beers over some ridiculous SaaS. TLDR: I don't like subscriptions.
