"But these types of clubs USUALLY have these 9s and 10s or are tourist traps."
Usually those kinds of clubs are called Show Clubs.
It is easier to hire younger and less experienced girls, used to lower mileage, in show clubs. They do tend to cater to business travelers.
I believe that many of DV's business models, and especially that used for Centerfolds, is like that. They get people who look for the name and are not interested in dives and mostly see the girls as objects for looking at.
Because of name and reputation, the clubs make money, and so do the girls.
But those clubs do enforce a looks standard, they want girls who will make money while still following the rules. And they often have lots of arbitrary rules. But sometimes these do have to do with local LE.
Dives, on the other hand, usually hire all who apply. They actually want some who will be the first to go way outside of the rules.
Where I live, it is very hard for such dives to operate because our LE Is very tough. So what we have of that is in underground venues. How lose things are depends upon the talent agent and the business operator.
A lot of it comes down not to regulation of the back rooms, but to regulation of the front room.
In what I consider to be the modern version of a clip joint, the front room is very regulated. While in principle then, there need not be any restriction on the back room, you get the worst arrangement of mileage versus cost when front room intimacies are prohibited, so it is just "wanna dance?". These are the kinds of places I would always suggest avoiding.
Front Room Makeout Sessions are the best indicator of a place worth visiting and worth spending money.
