Hmm. I own a Keurig machine, and am neither lazy nor spendthrift. I am, however, the only coffee drinker in the house.
Then again, we have 4-5 “Eco-Brew” reusable K-cups, and use them for not just coffee, but tea. . . and again, I’m the only Earl Grey drinker, the wife likes Lemon Zinger and the oldest is an English Breakfast enthusiast.
Rob, you MIGHT want to check your assumptions about consumers and their choices at the door. I don’t like the idea of wasting an entire pot of coffee, when I only wanted a cup. . .
