John Mayer is getting ready to play a gig tonight as part of the Bud Light Dive Bar Tour.
To celebrate, he decided to have a little fun with some bar patrons.
He wanted to test people on how long they would save a seat for their friend. It was pretty good...
That girl was rewarded with tickets to his show and she truly deserved them.
She wouldn't even let John sit there!
