Adam Woldemariam found the money-filled laptop computer case last month. He turned it over to his cab company's lost and found department.
The passenger who left the cash behind gave Woldemariam a $2,000 reward. Fellow cabbies teased that it was only a 1-percent tip.
But to Woldemariam's family in Ethiopia, the money means a lot.
"To send some money for his family, so it's a gift," said one co-worker. "That $2,000 means a lot to send back home."
The owner of the money says he won it at the Wynn Casino and accidentally left it in the cab on the way to the airport.
