Silly question but makes me curious.
* Why was she given so much regard when she came in
there are several possibilities
1. he is the son of a casino owner
2. maybe she is a great female gambler in your town but you don't know her yet (i think you should date her)
3. Maybe women gamblers rarely go to casinos, so everyone is a bit amazed to see them
4. Why don't you ask in person when you are at the casino? it will be clearer.
* How are female gamblers treated in your neighborhood?
in my country gambling is prohibited. so no women gamble in my area
