That would be bad but you could be lucky like Clark Griswold. He lost everything he had but the guy who was sitting next to him died and he dropped the winning ticket on the floor when he died! It could happen (not very likely, lol)
I have no gambling fear. I take in less money that I'm willing to lose. When it's gone I go home. If I win a substantial amount, I take it and go home. I don't go often, in fact, it's been quite a while since I was there.
