Dunkin’ Donuts is joining the coffee cup conversation. Starbucks’ red cups with the green and white logo jumped into the news when a number of Christians accused the company of waging war against Christmas. Now, Dunkin’ Donuts reps say their chain’s new cups are decorated with a wreath around the word “Joy” in big letters. Dunkin’ Donuts says the cups are carrying on a tradition of featuring “Joy” as part of the company’s “annual celebration of the season and holiday offerings.”
