Is this enough tip? On an check for $815.73?

If you look closely, you may recognize that signature (the person who forked over the small fortune).

He’s a United States Air Force veteran.

This from the Huffington Post:

The tip was left at McEwen’s on Monroe, an establishment that is just a 10-minute walk from the FedEx Forum, where the Spurs were set to play the Grizzlies.

The owner of McEwen’s, Bert Smithe, told mySA.com that “Coach Popovich has been in our restaurant in the past multiple times,” but would not discuss the particulars of his bill or when he last dined there.

“We don’t discuss anything that goes on when VIPs are in the building,” Smithe said. That said, he did then add that people had been discussing Popovich’s tip “in town,” whatever that means.

That’s right. The generous ole airman was none other than Gregg Popovich, the Hall of Fame coach of the National Basketball Association’s San Antonio Spurs.

Users on Reddit caught it while he stayed in the beloved Tennessee city (the Spurs took on the hometown team in the first round of this year’s playoffs).
