I have a friend who owns 2 cafes and his stock in trade is getting the best coffees from S. America...go figure. He explained to me how SB buys their coffee and they purposely do not buy the better quality beans, yet charge more because their cool...or something. He told me Dunkin Donuts, of all places has the highest quality out of all of the franchise coffee joints. How they roast it, is another issue!
That makes sense. In essence, it would be a scam then. Dunkin Donuts has good coffee, but it is always better at a local coffee shop.
