I recently visited a land-based casino after a long time to gamble, have some drinks and enjoy live music with a couple of my good buddies. Not long after we settled in, we heard one of the casino workers yelling at one of the gamblers. He said, "Sir please you have to leave now. You come here every day and you keep losing. Please be considerate of your wife and your newborn babies." The backstory is that this particular man is a very popular gambler at the casino not because of his winnings but because he keeps losing. Despite his losses, he would return to the casino the next day to gamble. From the story, his wife had just been delivered with twins. I would later find out that the casino worker is his nephew.
If you were the casino manager would you fire the casino worker for interfering with your business or would you ban the gambler from visiting the casino?
According to my understanding of OP's story, the gambler's nephew shouted at him as an employee where the gambler often goes to casinos despite the fact that every time he goes, he always loses at gambling. Maybe the casinos employee did that because instead of the money to be lost on gambling, the nephew would have preferred what he said without shouting, because that is showing disrespect to gamblers who go to casinos, and the assign manager for sure will get angry and he will talk to his subordinates and give a warning.
