how to tell a stripper no more ITC, only OTC

Im at a SC with no private rooms and officially bottoms always on rule. Semi-private LD area has a roaming bouncer to make sure your hands arent touching pussy or that you are fucking. In this SC 1 out of 3 girls DFK, but that is usually the most you can get. After going through like 20 strippers, I found an above average mileage stripper, that is semi-hot to me. A photo of her online is good to jerk off to (she tried to be a model), but she doesn't itch the BF inside of me. She refused to give me her name, but she did say she is an associate lawyer (WTF?) for a law firm but didnt give their name, they were the only law firm in that area she said their office was, and I found her in a group photo of the firm and her real name, I never told her I know her real name. She is 35 not 26 as she said, too old for me social. Anorexic skinny, no tats, no evidence of drugs. B or C tits. She did say she wants implants, I agreed, since she is a bimbo except for tits. This stripper is above average mileage. She lets me sneak small peeks at her pussy for a few secs, a few seconds of DATY, she does some stick shifting/HJ down my pants her hand directly on my dick's skin, no cloth inbetween, but completion is impossible due to the angle and I can't open my fly because it is semi-private LD area with others right next to us, and i can also unlimited FIV her in the semi-private LD area. This CF previously UNDERCOUNTed songs and just charged me $120 for ~30 mins in LD area, she told me, "you and me are always $120, I like dancing for you". Since the first time I saw her, it was 6 songs, when it was really 7 to 9. I just hand her $120 and she says thanks. No discussion over song count. 2nd to last visit, she commented how hard my dick was, and she wants to ride it, and she wants to meet me OTC, etc etc. Those comments were unusually explicit, so I asked for her number, she refused, and gave me her email instead. Emailed her with a "hi its X from X club, how are you?", no response. Next time ITC, she cried she made only $200 that week so far ITC. I thought SS to myself. I find that strange to believe, since I've had to goto other strippers twice in the last 2 months because she is with another customer. After we do our session, she always runs to the next customer, and when I take stripper #2 and #3 to LD area for test dances, I see my CF in LD area. She has no problems getting customers. CF has never spent time with me after the LD session, and she barely wants to socially talk before and keeps pushing for the LD session. Hence why I always LD 1 other random stripper that night b/c I want talking. CF also was like "Do you want me tonight? Do you want to talk to other girls instead? its okay if you do". Never heard THAT out of her before.This time ITC, she said nothing about dick size, nothing about OTC, much colder. I mentioned she didn't respond to the email but she stayed quiet, and I changed the subject. Also this time ITC, I gave her $120, she said "thats not enough, it was 8 songs". I didn't challenge it but realized I am getting into FS prices now with her and she thinks I am easy $. After 4 $120 ITC sessions, and 1 $160 ITC session, I think my CF expired or something. Not sure how to proceed. I want to say what happened to me was "I was single when I first danced for you, and you were hot enough that I allowed VHM with you, but I hooked up with a BF/SD and you are just a disgusting ATM for me now". At this point, I think I am wasting $ with her unless I can get her OTC. If she wont OTC, I need to move on. I think I got her too "comfortable" that I am guaranteed $. I think at this point, I need to tell her, OTC or nothing. There is no "friend" in her. She wants to "fuck" but not talk. I emailed her once. The no phone number thing, IDK if it is because she doesnt fuck customers, or is 35 and doesnt use technology, or because I didnt make an actual $ offer to her ITC, just a "lets get a hotel and fuck" assuming she will freebie fuck. Next time I see her ITC, what words do I say about doing OTC, should I just make a $ proposal like she is a whore "would you get a room with me for a $X gift?" and if its a flat no, I know my answer. If she tries to turn my OTC offer (gives me her # or a fake #), into ITC dances, what words do I say without making her stomp away angry and then I feel like I screwed up the negotiation? Just say "I can't buy ITC dances from you if we will OTC" or say a lie like "I just jerked off and Im not horny tonight". I know a stripper will say anything to get easy ITC $ aslong as the customer will keep giving it, but I need to close my wallet to CF ITC unless she will OTC without telling CF I will never spend $ on her again. One part of me says "if you dont say it right to her, its your fault she didn't fuck you", another part of me says "you can say it any way you want, if she says no, she wouldn't meet you no matter how you said it". HELP!!!
