How to loose 20000 in an hour

I think I have mastered the art of losing money. The latest gaffe is how to loose 20K in a hour. Its a two step process. Here it is ...

1. Bang someone's car and pay 5000 for the repair. Even when the other person hadnt asked for it.
   
2. Order a gaming console for a friend. Assuming that its 8000. And you actually end up paying 15000.

P.S.: Love the fact that I can pay this money without thinking too much.
