About 4 years ago I had filled out a suggestions card at Dunkin Donuts, suggesting that they carry soy milk. Shortly afterward, I received a phone call from DD. They told me that they would NOT be adding soy milk, or any other milk substitute to their menu, as they were not in competition with Starbuck's. My reply to them was: "You'll lose a lot of business. There are many veggie/vegan people, as well as lactose intolerant people, who will go elsewhere to buy their coffee." And I added, " If you're not in competition with Starbuck's, then why have you added espresso and cappuccino to your menu?" I think it's a demographics issue.
