Depend on which casino or what kind of people are those in the said casino , like for example if this is in Las Vegas when beautiful ladies are just hanging around everywhere do you think that they will be treated differently ? the answer is nope.
It depdns on how often a female visit the gambling place. Try ams differentiate between casinos and the gambling place the OP meant.
I think it is pretty rare to see a beautiful lady gamble in a space where people often disregard their looks. I remember visiting a physical casino and most of the gamblers there came with oversized shirts, without any regard in caring on the manner they presented themselves. What mattered to these people is their gambling activity and nothing else.
Which gambling space? I have seen a gambling space that are full of street people (I hope you understand the meaning of street people). Those kind of people do kit care about their look but gambling. But offline casinos is very different, meant for different set of people that care about their looks. Going to place bet with gambling operator for sport and sport virtual bet can be different, meant for people that do kit also really care about their look and for people that really care about their look.
