Which one of those did you partake in?

[Litzki1990]

If a gambler tells you he gambles just for fun then I'd tell you not to believe him completely because he's definitely not gambling just for fun with the maximum amount of money at stake. You can wait for the gambler to lose to be sure whether he is gambling for fun or he is gambling for profit. If after losing he wants to gamble more or if his mind changes then you will know that the gambler is not gambling for temporary pleasure. Gamblers say so but the reality is that everyone has an interest behind gambling and this interest is to win by gambling. If you are winning in gambling then you are happy but when you lose in gambling then you will be upset because no one can accept defeat if it means nothing.
