"We are very fortunate to call Bubba Watson one of our regulars," Pat Warner, Waffle House's vice president of culture, told ESPN.com. "After growing up in Florida and going to school in Georgia, we were glad to be there for him as he came up the ranks in golf. It's a testament to Bubba's character that even though he has two green jackets, he still comes to us for his grilled cheese and hash browns. All of the Waffle House Nation is proud today."
It's not the first time a Masters champ has given an unexpected plug to a food business. In 2010, a picture went viral of Phil Mickelson at a drive-thru of a Krispy Kreme wearing his green jacket.
