They "Dated". Don't date your boss. Duh!
There are also some clients (like myself) who don't want to party with someone who has partied with the boss. The two that I have asked gave given the "Eeeewwwwww" reaction. I am pretty sure they were both being truthful. It's not like I don't understand that these girls party with other guys, but something about being intimate with the boss just weirds me out.
Now this is something I really don't understand. What would be the difference between a working girl partying with another customer or partying with the owner? Not un less you're afraid she might give details of your party to the brothel owner while they are fucking. Other then that, I can't see what the difference is whether she fucks the owner or ten different customers.
The difference is the level of familiarity, and also the level of control that an owner has over the situation versus an average customer. Customers leave after a party, while the owner stays on hand to handle other business stuff. As the owner is still essentially the 'lady's boss', the lady may find herself in an uncomfortable situation if the owner requests an activity that she otherwise discourages. If she says no to the boss, will there be repercussions?
In most other industries, sexual advances are usually the grounds for sexual harrassment lawsuits. This is much more a gray area in the Brothel industry, but again not opening that door in the first place is probably less risky legally for the owner.
If a brothel owner has 'needs' on the sex front, they can visit the other houses instead, as other houses are available. I know of one brothel owner specifically that does this; i.e. parties at houses they don't own/manage, so as to not make their own ladies uncomfortable.
