You say the man is afraid of looking like a loser in the eyes of the girls, but that's how he looks to the girls when he leaves this casino after losing all his money.
How likely do you think it is that he'll come back to the casino after losing so badly? I don't think he'll ever come back, because defeats like that stick in a person's mind for a long time.
Even in the case of losing a man at gambling is considered a loser, so I don't think he will give up and quit gambling for a long time. Usually a man will be much more aggressive and show that he can bet large amounts to recover all the losses he has received in the past. The women in the casinos are only in charge of serving, not to the point of making things that beat losers and so on. That's why it's out of his control as a casino waiter.
