It doesn’t matter that the drink we knew as Dublin Dr Pepper isn’t really going away (or that a lot of it was not bottled by Dubin Dr Pepper in the first place). It’s a part of Texas history and of a Texas town’s identity. You don’t mess with an icon, especially in these parts, and judging from the (still-raging) activity on Twitter and Facebook, the Dr Pepper Snapple Group in Plano has a lot of unhappy customers (and former customers) on their hands.
