This is the sort of story that best gives you the sense of the kind of guy Dave Grohl is. It also makes you wish that you were the bartender serving him and his bandmates. The Foo Fighters frontman and the band were at the iconic Rainbow Bar & Grill on the Sunset Strip. While there, they purchased $333 worth of beer. Grohl admits he was too drunk to calculate a tip. So he just doubled the cost of the beer. That made the total $666.
That decision by Grohl also meant the bartender was getting a $333 tip! It also means that Grohl and the band drank a lot of beer.
