You can by beer to have fun and not seeing it as a waste of money. You can give a friend little amount of money in a way he may want to give you back but you will not collect it as you see it as small amount, telling him it is a small amount of money. Only such money like that, that are small in amount set aside should only be used for gambling. That is the meaning. The fun you see there does not necessary mean fun. Just like an ideom.
If every gambler thought like this then I'm sure they would be more responsible for playing several bets every week and we are used to spending small amounts of money without thinking about returns. But the problem is that gamblers don't think like that because they think they will benefit from winning and even though they consciously know that gambling is always closest to luck. Just a few views and not trying to blame or say gambling just has to be done responsibly, but I take more pleasure in seeing gambling activities.
I prefer this kind of gambling and spend a little money for fun, not to chase winnings every time I want to gamble. So that whatever happens psychologically we are not too disturbed and if people can make a portion like this in gambling then I am sure they will be much more responsible in the gambling they play.
