No it doesn't, if a girl is good and offers a good service she can start gaining regulars from her first week on AW
Obviously not all return, but you have been around for quite a time now and the fact you appear not to have built up sufficient regulars speaks volumes for your service.
You have just said it yourself, you start
to gain regulars, therefore it does take time to build a regular client base.
It is important to attract new customers, that's how they become regulars in the first place.
If it was so easy and quick to become independent and so black and white as you put it, then there would be no such thing as agencies in the first place.
You can't honestly believe that every man who punts will want to see the same girl over and over, some like it that way, some don't.
I am sure I have read various threads on here, to prove that.
Working in Reading, I see many clients who do not even live in the area, and are just around on business, so it is not as clear cut as you seem to think.
Of course I have regulars, there wouldn't be much point in working if I didn't.
