I used to be a hard core caffeine addict. And I say caffeine addict, not coffee addict. I don't actually like coffee all that much, but I still drink one cup a day, in the morning, to ward off the headaches.
We now have a Keurig in our company break room. There are several brands of Keurig coffees that are present. Predominantly Starbucks, Green Mountain and a few others. They are so bitter. I hate them. There is this Donut Shop coffee that is actually drinkable. Much in the same fashion that the dirt cheap McDonald's coffee is more drinkable than Starbucks.
