Think Starbucks is taking over the world? Not so fast. A new study shows that the most loyal coffee drinkers come from, of all places, McDonald's. Insight firm Customers DNA polled 15,000 quick-service restaurant customers about their coffee-buying habits, and discovered that while more than 50 percent of customers who go to Starbucks and Dunkin' Donuts also go to competing chains like McDonald's, only 29 percent of McDonald's customers will break the habit to hit up Starbucks or Dunkin'.
When it comes to your daily cuppa joe, where do your loyalties lie?
