Yes. If it was shit coffee.
I literally bring my cafetiera (old school) to work, preloaded. And have my little bunion burner I attach to a small butane can and make a fresh 3 cups of espresso on my morning break.
Not for cost savings, I just can't separate myself from my fiat for shit substandard Canadian coffee. Decorated as "chic" so they can + inflation, literally charge me 10+ $.
Fuck that. Little more work? Sure. It's also hilarious that all the people at work find it hilarious and the most italian thing they've ever seen lol.
Like @pipe said - you live once. I ain't spending that time drinking shit, overpriced cafe. Respect yourself, and more importantly your time. How much energy do you need to produce and spend to pay for that coffee? Was it worth it? That answer is in you.
