I edited a piece last week on the same subject. It's just downright greed.
I said to the writer he should do three things, buy a de Longhi coffee maker, second-hand will be fine, buy organic coffee beans, and a travel mug. I mean, how long does it take to make a cup of coffee, for heaven's sake? In six months he's have paid for his machine.
We very rarely buy coffee out. Our home brew is the best.We have had our coffee maker for quote a few years.
Most coffee you buy out, sucks, temp is wrong, small serves, a business going out..of business.
