When Jordan Smith got her tab after breakfast at in Winston-Salem, N.C., she was pleasantly surprised to find a 15 percent discount — for "praying in public."

Smith, on a business trip, that she and her colleagues "prayed over our meal and the waitress came over at the end of the meal and said, 'Just so you know, we gave you a 15 percent discount for praying.' "

Smith then snapped a photo of her receipt, complete with a line item for "15% Praying in Public ($6.07)" and posted it to her Facebook page. Not surprisingly, it's gone viral.

Some people wondered if it was just another social media hoax, but Shama Blalock, a co-owner of the diner, confirmed to NPR that "It's for real; it does exist."

“When you pray, you are not to be like the hypocrites; for they love to stand and pray in the synagogues and on the street corners so that they may be seen by men. Truly I say to you, they have their reward in full. But you, when you pray, go into your inner room, close your door and pray to your Father who is in secret, and your Father who sees what is done in secret will reward you. (Matthew 6:5-6)
