A Texas man's tweet helped drum up business for his dad's new doughnut shop in Missouri City.

Billy By posted photos of his dad's empty doughnut shop on Saturday, writing that he was "sad" with the low turnout for the grand opening.

The tweet quickly went viral, and on Sunday, Billy's Donuts completely sold out of doughnuts and kolaches for the day.

Later that day, By posted a new photo of him and his father grinning from behind the counter, with very few pastries in the display case.

"Just wanted to update y'all! We completely sold out of donuts and kolaches! You are all amazing. I can't thank everyone enough for coming out and supporting local businesses. This means too much to my family," By wrote.
