One detail: this change only affects the COMPANY owned stores. Franchisee owned stores are not affected. I tried to find info about how many/which of the stores are franchisee or company owned and was unable to locate such info.
There is a longer story
here (from the Diedrichs web site).
BTW: I was unaware that Diedrichs owned Gloria Jeans brand as well. That is where I had my first candy coffee (a mocha) many moons ago.
