Fans were surprised to see Post Malone and Riley Green when they stopped by Loser's Bar & Grill in Nashville recently. They threw on aprons, jumped behind the bar and started making drinks for some surprised patrons. One person said that Post made screwdrivers for her and her friends. Riley grabbed her phone and took a group selfie with the bar. Riley has made a few surprise appearances at Loser's over the years. The establishment is attached to his own Duck Blind bar.
