I think that there should be no such thing as blaming someone for our losses , because we must be responsible for our actions, If we play in a casino and lose for whatever reason, it is our own fault, and no one else's.
I agree, blaming others for your own losses is a sign of irresponsibility...we must learn to hold ourselves accountable for the losses that we incur in gambling because we are the ones that made the decision of staking that amount of money....this is why it's very important to always be cautious of our stakes, gambling with what you cannot afford to lose can end up becoming a problem
