Drinking beer is almost a rule in golf, especially if you haven't had a good day on the course. It is a tradition that even the biggest stars cannot escape, and here is Brooks Koepka to prove it.The five-time major champion had a horrendous performance at the 2025 PGA Championship, where he missed the cut by eight shots. The situation cried out for a beer treatment, and Koepka wasted little time in providing it.The X user, identified as 'Keith Blazkowicz, PhD, MD', was lucky enough to run into Koepka in the store while the LIV Golf star was buying his beers, and he wasted no time in posting it:"Went to QT to grab some beer after a rough 18 holes. I think this guy might be doing the same..." Blazkowicz wrote.The post went viral in an impressive way, considering it received more than one million views and more than 14,000 reactions in less than 24 hours. Even more impressive is that the author of the post only has 227 followers and did not even tag Koepka.In the picture, which was taken on Friday, you can see that a clock reads 8:10 p.m., meaning that less than three hours have passed since the player finished the second round at Quail Hollow. There is no doubt that not having to play the next day has its benefits.One detail that did not go unnoticed by fans was that the West Palm Beach, Florida native's beer of choice was Miller Lite, even though he is sponsored for a rival brand.Koepka signed an endorsement deal with Michelob Ultra in 2017 and, as far as anyone knows, remains one of the brand's top ambassadors. The 35-year-old has made numerous promotional appearances for Michelob, including two Super Bowl 2022 commercials.The five-time LIV Golf winner carded a 36-hole score of 9-over 151, which prevented him from playing the weekend at Quail Hollow. His overall performance included six birdies, 11 bogeys and two double bogeys, with negative stats in five of the six components of the Strokes Gained series.This is Koepka's second straight missed cut in a major championship, having done the same at the Masters last month. It is also his eighth consecutive major without a top-10 finish, the first time that has happened in his career.More Golf: Jon Rahm soars into PGA Championship contention after masterful Saturday
