That experience will haunt them even while they're sleeping lol.
That is actually what keeps gamblers coming back for more. Because they will want to chase the losses. They want to recreate whatever it is they had before they spent it all thinking yes they are better now and they will take care of the profit once given but it is never given to them again. They will keep playing again.
Nobody losses a fight and chooses not to overreact or figure out why they did, watch boxers, and wrestlers how bad they feel after losing to someone they thought wouldn't beat them to a TKO. The negative results of gambling is what actually takes us back to play more, let's be genuine to ourselves, it's not easy to accept failure or defeat. New players who are not used to the system fall prey by far to this problem and lose so much in a session just to justify their self consciousness and the fact that they could fill up a dry bankroll in a fresh game which then leads to chasing the losses.
