I have been to many AMPS in the San Mateo Area for many years, but not Avee 9 Spa . I am usually visiting in a weekday morning so my experience may differ from those that might go in the popular evenings. So in all my limited experience it is most common to have just two providers working during that time. So there is not much selection and one is often busy. But I always call for an appointment and ask for a specific girl. Either one with good reviews, or one I have prior experience with. So the idea of a line up is just not realistic. If I am hungry, have money and have a open time slot, I want to know what I am getting.
