Music superstar Post Malone helped one Houston hospitality worker have a very Merry Christmas when he left a $20,000 tip during a visit to The Railyard, a neighborhood bar near River Oaks.

Malone, in town to participate in Beyoncé’s halftime show at the Texans-Ravens game, stopped by the bar with fellow artist Shaboozey. When the bar’s regulars picked up his tab, Malone requested that he be charged a small amount so he could leave a tip for bartender Renee Brown.

Needless to say, the single mother was shocked by what she saw on the receipt.

"I try to go above and beyond to take care of all of our customers, and loved seeing them interact with Post Malone when he visited — he was so genuine and made everyone feel comfortable," Brown said in a statement. "His generosity with this life-changing gift blew me away. This definitely wasn't the Christmas Eve I was expecting, but one I'm forever thankful to have had."

For those unfamiliar, the Railyard is a casual neighborhood bar with a devoted group of regulars who appreciate its low-key atmosphere. It offers happy hour daily from 4-7 pm and all-day on Sunday. With its proximity to posh hotels such as The Post Oak, the Houstonian, and the St. Regis, it has seen its share of celebrities, including David Spade and Keifer Sutherland, according to a release.

“We are so grateful for Post Malone's generosity during his visit," Railyard owner Trey Melcher said. "One of the most amazing things about this bar is that you never know who is going to walk through the door. In the past we've had visits from celebrities, but this unexpected act of kindness made all of our holiday seasons brighter."

Malone came to Houston in October on his F-1 Trillion Tour. Sadly, his BIG ASS Stadium Tour with fellow crooner Jelly Roll is only going to San Antonio and Dallas, but he could be part of the lineup for this year’s Houston Livestock Show & Rodeo, which is being announced this Thursday, January 9.
