One of Aurora Kephart's regulars at Conway's Restaurant and Lounge in Springfield often tips her with Keno tickets from the Oregon Lottery.

The man, who wishes to remain anonymous, asked Kephart to choose two tickets one Tuesday night.

When she checked the numbers, Kephart's first ticket won $5.

The second turned into a $17,500 gratuity.

"The look on his face was incredible," Kephart, 25, told The Register-Guard newspaper. "I automatically handed it back to him; it was his ticket."

But the man wouldn't take the ticket and made Kephart sign it so she would be the only one able to collect the prize.

Kephart said 80 percent of her customers are regulars, and they were excited for her.

"The reaction was crazy," Kephart said. "Everyone was so amped up."

With the bar busy, Kephart went right back to work, excited by the big tip. The next day, she claimed her prize at the Oregon Lottery office in Salem.

And to prove that generosity works both ways, Kephart said she later gave the man a percentage of her winnings.
