Las Vegas taxi driver Gerardo Gambia recently found a paper bag filled with money that was left behind by a passenger.

According to the Las Vegas Review-Journal, Gamboa was making a pickup Monday at the Bellagio Hotel when a hotel doorman noticed the brown paper bag in the back of the cab and handed it to him.

Gambia thought his recent not-dressed-so-well passenger might have left behind a bag of chocolates, but when he reached into the bag, the cabbie pulled out $15,000 in cash (video below).

When he counted up the money that was left behind, it totaled $300,000.

Instead of keeping the cash, Gamboa called his taxi dispatcher and took the money to cab company's office.

Eventually, Las Vegas police and casino officials linked the money to a well-known poker player, whom they did not identify.

"I don't care from $10 to higher. My dignity is not for sale, and that's the way I am. That's the way our parents taught us when I was a kid," Gamboa told CNN. "All I wanted to do was just call my dispatcher and return it, and this is the only chance I have to show cab drivers in Las Vegas are not bad people."
