At first glance, this would seem like insanity. BUT,
This Christmas my wife bought me one of those one serving coffee makers which I have fallen in love with. We are starting to get a small collection of different brands and some ground from beans. This will probably be as exotic as we will get, except you can purchase pods of coffee so you don't have to measure it out yourself, but I can almost understand how you can get addicted to the beverage. Read the figures and it adds up.
