"Owners of so-called girly bars also fine the sex workers heavily if they fail to show up at work for a day or two."
So there shouldn't be a penalty if they don't show up for work? If they don't do that, girls will not show up for work half the time! If you can't fine them, then the only option is to fire them and soon you will have no employees.
"Sometimes, operators deduct money from the commission the women make on drinks bought for them by customers, hoping they will be too drunk to notice."
This is impossible (at least very hard to do). Girls get a commission slip every time they get a drink. Girls watch out for each other and it wouldn't go unnoticed. They should worry more about drunk customers bills being padded. Where is the protection for us??
