How do you see the father? Was he right by rejecting the son gambling win?
It depends on the actual perspective.
There is nothing wrong with gambling money in this case, but indeed for some people something like this will definitely cause controversy, especially for those related to spirituality and belief.
In some conditions, in my area, this kind of thing still happens a lot because parents believe that money from gambling, which is actually not allowed, according to them, has no benefits, which actually creates a condition where we get bad luck in the end.
It may happen to the father though in this case he may need it but he has a degree of discipline for gambling money because he may not gamble either.
Regardless of right or wrong, everyone has their own views on this matter and indeed we also cannot justify or blame the father's determination to refuse the money because he has his own commitments.
There are people who would really stick into their principle on which no matter how small or big the amount that they do get from gambling but if it does really involved on things which you do really prohibit or something that you cant deal off with then for sure you would really be having those impressions.It is really just that impossible though that someone could really just simply reject specially we are talking some significant amounts of money on here.This does proves out that there are really still people who cant be bought and just sticking into their principles on what they do believe on.
