My Filipina wife is a dancer, and the club has booths similar to this, but no glory holes or doors, where the girls are allowed to take their customers for privacy. The booths are monitored my both staff and cameras, so it's not complete privacy, but it gives the girls and opportunity to make good money. They have a quota which has to be paid by end of shift, so there is a LOT of hustling going on. The booths are rented by the client - 20 dollars for every 20 minutes - and the services and fees are negotiated by the dancers and their clients.
She is a super sexy and good looking woman! I will bet my house that she's a smoker though. I happen to not like smokers, but I'm sure everyone else does.
