Thanks to astronomers, Krispy Kreme will be giving you a free doughnut. Let me explain. Once astronomers got the first-ever image of a huge black hole at the center of the Milky Way, Krispy Kreme decided to celebrate. So because the image looks like a glazed doughnut, they've decided to giveaway a free glazed doughnut to customers. Just stop in and ask for your doughnut. What are your top three doughnut flavors?
