Personally, if I were to gamble, the thing that could make me lose my temper and fight with fellow player is the moment they decide to pull a dirty trick on me or to start disrespecting the people that I love for whatever reason they have.
If they disrespect my friends or the game or club I supported is not enough for me to engage them on a fight, but the worst they could do is to involve my family, then they will see another colour shade of me from the place instantly, i dislike seeing people having disrespect over my family or bullying them with their dirty mouth saying all manner of shits, that alone is a means to arose the vexation spirit in me.
I will not really let is slide because disrespect is something I cannot tolerate even if how famous, good looking, or rich you are. If you cheat on me or disrespect my loved ones, expect that there will be an argument. But of course, I will handle it with dignity at first, I'll make sure to be calm and be the bigger person but if you continue to be an asshole, then you'll have to face my wrath.
Don't be surprised that some gamblers don't mind with the kind of dirty acts because they were used to it already, that kind of a lifestyle is what they lived in daily, they know their gangs and someone like me who does not belong to them cannot tolerate such manners, this could result into a right as well, but we also have to be mindful of the kind of people we take as friends or where we choose to engage physical gambling experience.
