Brian Maixner, a waiter at the Wichita Kansas ‘Doo-Dah Diner’ got an unexpected tip from a total stranger..$25,000 to fix his teeth. Fred Boettcher, the generous customer, said his Christian faith is at the root of his charity. “I can do this and I should do this” was his simple thought. (By the way, it’s about the tenth time he’s had that thought and acted on it.)
