Cash or conscience?

On my first post, I asked if you'd keep a stray $100 or look for its owner. Now, let's step it up a notch.

Pretend you're a New York cab driver (who takes a bath), and you've picked up an executive and you're bringing him to JFK (the airport).

On your way to the airport, the businessman calls a lot of people, talking about important business stuff. As soon as you reach the airport, he hurriedly pays his fare and exits the yellow cab.

You murmur your thank you, and watch him enter the airport. You're about to speed away when you see a black briefcase in the back seat.

It might be a bomb. That guy might have been a terrorist. With extra caution, you open the briefcase.

What's inside astounds you. Cold, hard cash. $1 Million in cash. There isn't any defining mark or name on the briefcase or the cash.

Think about it: if you keep this money, you can ditch this friggin' cab, start another business and never have to work again in your life. But your conscience tells you to hurry into JFK and look for your passenger.

Would you keep the money, look for the person, or would you have done something else?
