I'm sorry for sending this post on a tangent, but its a personal grievance I have with them, pokies really. Ive watched my parents waste way too much money in the things and had friends who spent every penny not spent on essentials. I guess its a better experience than some who've lost their partner's homes or has led to robbing their employer and subsequent gaol, but it was enough to put me off.
I get some people will go for a night out there and enjoy it for just that. That's great for them. But for those with gambling addictions, there is no stop button, no self-restraint.
I don't have the answer, but perhaps a cap on money spent before entering would be a start. Make it a contained experience, with the cost upfront. You might argue it inhibits your freedom, but it would help prevent a lot of heartache.
