Here's my #coffeechain submission for today.
Probably my 5th or 6th one of these, and I got motivated before taking the picture and drank some of it.
Victor Allen Italian Roast k-cup (cheapest I can reliably find, which is about 31c per cup). It is cheaper at Big Lots than Amazon.
Tap water from my en-suite bathroom sink.
Farberware cheap knock-off k-cup brewer.
Cup is a fall collection reusable Starbucks plastic cup.
Utility. Commodity. Convenience. Savage.
