WICHITA, Kan. (AP) -- A Wichita mail carrier is still trying to figure out how to thank a business owner who returned his wallet with $1,300 and all his credit cards intact.

William Fox lost the wallet Sept. 12, just after had cashed his paycheck so he could make a house payment. He searched frantically for several days, even posting notes asking for help, filling out a police report and announcing the loss at the Munger Station post office where he works.

Fox became convinced the wallet had been stolen and began replacing his credit cards and driver's license, The Wichita Eagle reported Thursday (http://bit.ly/QNZu17).

Then Fox received a letter a few days ago from Flying Donuts in Wichita, telling him to stop by.

Fox went to the doughnut shop on Tuesday.

"I've got something for you," Flying Donuts owner Tricia Davis told Fox, handing him his wallet with the cash, credit cards and his licenses still inside.

"It was unbelievable," Fox said. "It just seemed like I could have flown out of that place."

Fox stopped at the store Sept. 12 to buy doughnut holes to eat while he delivered mail. While paying for his order, he put the wallet next to the cash register. Then he left the store.

No one noticed the wallet until the man who picks up the leftover doughnuts every day for the Union Rescue Mission spotted it that afternoon.

"It was right in front of the register," Davis said. "The register's high. I can't see what's on the other side of it."

The wallet didn't contain a phone number and a number for Fox in an online telephone directory was disconnected.

Davis waited for two weeks, hoping Fox would return to the store.

She finally sent a letter to the address on the driver's license. She asked for a photo ID "to make sure it's the right person who claims the wallet," Davis said.

Fox, who has worked for the post office for 27 years, said he still wants to give Davis some type of reward.

"She's the most generous," he said, his words trailing away. "I've never heard of anything like it."
