To become a responsible gambler is a personal choice. Casinos have nothing to do with a gambler acting in a contrary manner. They give warnings and promote responsible gambling, but they can't influence the gambler from being irresponsible.
We know they are looking for more profit/income, but I believe they don't want a gambler to suffer big losses because of their wrong gambling approach. We can't say they don't care about gamblers. It happens that casinos can't control them. We can't blame the casino for our addiction because we have the option, yet we choose to live with the wrong approaches.
It is a fundamental right that cannot be violated and it makes us bold enough to face the results of any action we perform in life since it is a right of choice. I understand that until we manage to rectify our understanding of pleasure, we will not be able to resolve the issue of cornering service providers. You show how individual responsibility is the major aspect of ensuring we do not dig the trap of self-misery. We should realise that we are left with all the major decisions and it is not the environment giving us the means to do it.
It is regrettable that even after seeing so many gamblers fall into addiction, many still refuse to change. When they suffer the consequences, they end up blaming the casino for what happened to them.
What is even harder to accept is that many never learn from their mistakes. That is why giving them warnings every day is pointless, as it won't work. Gamblers have different mindsets as well. They gamble for money, not for entertainment, which I believe will be difficult to change until they open their minds.
