Swearing for the situation he goes to a taxi driver and asks:

I have lost all my money, please give me a ride back home for free.

Fuck off, no money, no ride.

The next day the guys come to casino again and this time he successfully won all the money back and 10 000$ extra.

Hi goes out of the casino happily and sees five taxis, and the last car is the one, which refused to give a ride for free yesterday.

He goes to the first taxi and says:

Will you take me home for 100$

Sure!

But when you take me there you'll have to do the blow-job as well

Fuck off, man..

The guys goes to all next three cars and the story repeats.

Finally he goes to the last taxi driver, who refused to help a day ago, and says:

Will you take me home for 100$?

Sure!

Deal, but you have to pass through those other four taxi drivers very, very slowly.
