Just because someone is predisposed to an addiction doesn&#x27;t mean that you as someone that interacts with this person doesn&#x27;t have any responsibility in that situation.<p>For instance in many places bartenders are bound by law to not give more alcohol to people that are already drunk.<p>The biggest problem I see with gambling is that the Pareto effect shows an ugly face there: often it&#x27;s just economically feasible for the operator because of the addicts.
