You make many good points, Draco, but for some, the thrill of the hunt is as enjoyable as the session itself. Like others, I have one or two favorites which I return to every now and then, but for the most part, I usually find myself trying out new places. I rarely return to an AMP unless I know I can get the service I want for the price I'm willing to pay, and even then, I usually find myself looking for new places anyway.
Motel incalls can be a hassle, but if its a provider with which you have an established relationship, it's usually not that difficult. I'm fond of Nature, for example. She's not the hottest girl on CL, but I'd rate her as a solid 7 and she has very reasonable rates. She moves around a bit, but can usually be found not too far from the nass/suff border and I just have to call her to get the location. Plus she's really cool, doesn't rush and is fun to spend time with.
Sometimes, I'm just in the mood for an AMP though, more specifically for a new AMP, one where the extent of services offered are unknown. I like to see how far I can push the envelope. I get off on that more than the act itself, thats just who I am. I'm not shy about telling them what I want and what I'm willing to pay for it. I will routinely offer 60 for BBBJ. If she says BBBJ is 80, only HJ for 60, I say no I only give 20 for HJ. If she then tries to negotiate 40, I get up and leave. If she does the HJ for 20 and does a really good job, I may just give her 40 anyway as it is within my budget, but I will never spend more than 100 total. I have other expenses and job security is not what it was five years ago.
I understand their side of it and I realize they get little or none of the house money. But what you said about opportunity cost applies to them as well. While independents can potentially make more money, most AMP workers speak poor english and would not be able to function as an independent. They are the ones that need the AMP setup, not us, and unfortunately, they have to accept that the house is taking a cut of their money. Some mongers will pay them more, and I don't fault them for trying to make as much as they can, but as far as I am concerned, I have a set amount I am willing to pay and they can take it or leave it. And if I have to go home unsatisfied, then so be it.
