From Golf Digest...
"The worst collapse of Mickelson's career was complete. He had lost the 2006 U.S. Open by one shot with a double bogey on the final hole.
But that's not where the story ends. After making the obligatory media stops and signing autographs, Phil sought out Winged Foot's staff members. He thanked them for their work, shook their hands, and discreetly handed each a wad of cash: $1,000 here, $1,500 there. Phil had spent a lot of time preparing at Winged Foot before that year's Open, so he wanted to thank everyone.
It's reasonable to estimate that Mickelson handed about $10,000 in tips to staff throughout the week, according to people who were there. But as he was driving away, Phil felt compelled to turn the car around. In the craziness after his collapse, he realized he had forgotten to tip a handful of the locker-room guys, and he didn't want to leave without taking care of everyone.
"Phil is one of the most generous men I've ever had the pleasure of knowing," says Doug Steffen, the director of golf at Baltusrol Golf Club, where the year before Winged Foot, Mickelson had claimed his second major championship. "The way he takes the time to meet all the staff and thank them for their work, I've never seen anything like it.""

I happen to know of him taking an entire pro shop staff out to dinner to thank them.
