It's not only gamblers that gets angry and disturbed when things are not going how they planned, a person that has anger issues will exhibit it anywhere. A gambler that is composed will not show anger and frustration when they lose all their money, they will remain calm and composed. The guy in the OP story is not a responsible gambler because was not supposed to use money that was budgeted for something else to gamble. People should really understand that gambling is not a short cut to double your money, it's a place where you try your luck to win (increase) your money but there is no guarantee that you will win.
