It's just a reasoning for him to take his losses back easily. It's always been said to gamble responsibly.
And whether that guy has money or not, I think that whichever situation he's in, he'll do this to annoy the casino and will still gamble irresponsibly.
He's not vulnerable, he's even taking advantage of the situation but no matter how hard he try, he'll lose this battle.
This is giving him the spotlight and bad reputation to himself and his family.
Many people have completely separated from their families because of gambling because when a person becomes addicted to excessive gambling, their relationship with their family starts to deteriorate. A person never thinks while gambling that if he loses in gambling, it may not be possible to recover those money in any way. Gambling is more dangerous than a serious addiction. Those who become addicted gradually become destitute.
The one problem I have with addicted gamblers is taking advices, it's always like they cut off their ears before they start gambling so that anyone that try to talk them out of their irresponsible behaviour they won't be able to hear a thing.
I was happy when I saw a popular betting company telling his customers to be gamble responsibly yesterday on live TV, this is actually the first time I've seen such in my country but at the same time gamblers don't care, some will think that it's a trick to make them win less amount of money.
