Somebody brought some Starbucks coffee into the office and made it in our regular drip coffee maker. Now, our town water is fairly nasty, so it was not a fair trial, but that might have been the worst coffee I have ever tasted. I've also tried coffee made at Starbucks stores. I find it almost undrinkable. On the other hand, I will go out of my way to find a McDonalds when I want a cup of take-out coffee.
