From the OP's story, the person only wanted to gamble and didn't want to cause any trouble, so the officers felt safe as long as the person was gambling with their own money. Moreover, there are no rules whatsoever that prohibit someone in shabby clothes from coming to an offline casino, it's just that it might make you uncomfortable other people see it. In my opinion, not everyone who dresses shabbily is someone who has a mental disorder and it could be that this person is a gambler who is addicted so he doesn't have time to take care of his clothes and take care of his cleanliness, he is just trying to get money to continue gambling, hoping that one day he will get lucky the big one.
If someone is clearly seen having a mental disorder and is causing trouble, officers will definitely take action and try to evict the person, because it is impossible for workers at the casino to just watch a person with a mental disorder enter the casino, which will make the customers uncomfortable. So in conclusion, as long as the gambler still has enough money just to gamble, I don't think it's a big problem, after all it will increase the profits of the casino itself.
Yes, that means the casino can accept someone in shabby clothes to come and gamble in the casino. Based on what has been said, the guy didn't make a scene in his casino, so the officers didn't mind if he gambled. Moreover, after gambling, he will leave the casino straight away without making a fuss about other people who are also in the casino and gambling. Unless the person often disturbs other players and makes a fuss, perhaps the officers will no longer allow him to gamble at the casino. Not all people who dress shabbily indeed have mental disorders because there could be people who dress shabbily. But he turns out to be a millionaire who gambles and doesn't want anyone to recognize him in gambling so he decides to dress shabbily. The important thing is that everything will be fine if the person doesn't disturb other players.
The officers at the casino must have recognized the people who were their regular customers because that was their job. And I think there are even people who dress neatly but often disturb people who are gambling and the officers have to be firm with them and will not allow them to return to gambling at the casino. Anyone can come to the casino as long as they are old enough to gamble and not disturb other people. The officers who work at the casino look after this because they also want to avoid any problems while they work there.
Its shallow to determine a gambler's worth or intentions by their clothes. Although behaviour matters more than clothes, the casino's non-discriminatory attire code is admirable. Here, society's distorted reliance on appearances is evident.
Officers are essential to a healthy gambling environment. They must be vigilant for unruly customers regardless of outfit. Conduct matters, not clothes. As someone familiar with gaming dynamics, I think this approach is vital to a courteous, fun gambling environment.
Finally, the idea that shabby-dressed people could be wealthy defies prejudices. Remember that appearances can be deceiving, so never underestimate anybody solely on their appearance. This perspective enhances our awareness of human variation and life's unpredictability.
