I can't say if I have seen any women playing in a casino in front of me, but I have seen them mostly as dealers in various live games which shows that women are aware of the gambling field and are involved in this industry at a bigger pace.
I have seen a female gambler; in fact, I have a lot of them now as friends. In the new area I just moved into, most of the newlywed neighbours are into gambling, and they don't hide it at all. I don't know if their gambling habit is as a result of them working in a betting shop or if they just naturally like to gamble, but one thing is very common among them: they know the amount and limit to what they can gamble a day.
Except for one of them who always complains of having shortages in the shop almost all the time because she uses the bonus that was supposed to be left for her as her attendance for gambling and uses it up to the extent that she doesn't realise when she has gambled above that amount, and I believe this is as a result of getting involved in virtual games, where for the game run for less than 5 minutes, one particular game has ended, which can make some one run like 10 bets in less than 30 minutes.
Aside from this particular girl, all of them are responsible gamblers, and they don't gamble even with their earned salary; all they use most of the time are those bonuses that the shop assigns to them as their daily tips.
