I want to asked here.. What could make you stake bet with a motorcycle or any physical properties knowing too well that when lose you can't afford to let go your motorcycle or property. How could this act be properly prevented, or does it mean that the betting shop should stop accepting people using anything not less than money to stake bet or what? I have seen many worse cases where people gambles uncontrollably, I was so much embarrassed seeing people behave this way.
The physical belongings in this case were useful as collateral, so the betting shop was assured to not have a loss, even if the gambler refused to pay for the bet for some reason, like the one presented of not having money to pay for it. I don't think it's common for betting shops to accept belongings and patrimony to allow the gambler placing a bet, but in cases where the gambler is a scammer, they go after his goods and patrimony. That happens all the time always a person doesn't pay his debt off. So the justice system goes after any goods on his name, seize it and then transfer to the creditor.
It's the responsability of the gambler to know when to stop or when to avoid gambling. The gambler can't expect the betting house to forbid him from gambling because he is an addicted one. The betting house doesn't care at all to say the truth, as profit is what they seek, besides the fact it would be too time demanding to investigate each customer to find out if he is a problem gambler or not.
