Gambling with someone else's money is a very bad idea.
Gambling with your own money is a really bad idea except you just have so much and you are willing to give some out, let alone, gambling with someone else's money? That is a horrible thing to do. It is not just a bad idea but an extremely worst idea. It is more like loosing in 2 places. Loosing your soul due to addiction (cause that is the only reason I can picture someone doing something that crazy) and then going into more debt.
