At Loser’s Bar & Grill in downtown Nashville over the weekend, Post Malone and Riley Green got behind the bar and started serving up drinks to the thirsty and star-struck patrons who were lucky enough to be in the pub that night. The two country superstars surprised everyone by tying on aprons and becoming makeshift bartenders, taking orders and mixing drinks for their shocked patrons. According to one fan, Posty whipped up a batch of screwdrivers for her and her friends, while another person said Green took her phone and took a group selfie with their friends. There was even a lucky bachelorette party at Loser’s that night, taking photos and videos of  Green and Malone behind the bar serving up drinks for everyone out for a good time on the town that night.
