John Hamm, hanging with Zach Galifiniakis,  stopped for lunch at Tupelo Honey Cafe.

Their waitress Abby Swartz recognized them right off the bat and fought the urge to turn into a crazy fan. John must've appreciated it, because he said to her:

"Take this wristband and go to Bonnaroo, this will get you anywhere you need to go."

Abby was dumbfounded by this gesture as she told Chattanooga news website Nooga.com

"I mostly kept to myself. But there were times when I would just smile and think, 'There are thousands of people here, and I am the only one who is, basically, Jon Hamm's stand-in,'" she told Nooga.com. "Jon Hamm is amazing, and I would love for him to know that he made my life."

Then so Abby had some money to spend while she was there Galifianakis left the her a 250% tip.

The wristband gave Abby backstage access to Bonaroo!
