Keep in mind, the goal at holistic places is to get the customer off. Some guys are very difficult and can take a long time to bust so often the girl will start the fun stuff a bit early to give themselves some buffer. Normally this is not an issue once the girl knows you. Once the goal is accomplished and if there's not a lot of time left, say 5-10 minutes, it is true they might start wrapping up. Not saying this is right but pretty common at holistic places. Of course, some girls are better than others...I suspect some of the semi-oriented girls like Cici and Bee would be better at staying until the end.
BMR still offers the best rates though...most holistic places charge more on the room rates.
