Awkward

A couple of months ago, I'm texting "K" about meeting up. She's willing to meet before she goes to dance, or I can just meet her at the club. Since I've never had the pleasure of her completely naked, carnally active body, and since this is a weekday when I don't really want to stay out late anyway, I suggest we meet at the club, and if things work out there, we can schedule a more intimate meet up later in the week. After I sign off, I notice the name right above hers in my phone book, "J". I originally met her in a club, but hadn't seen her there since, and she didn't answer the initial texts I sent her. On a whim, I texted her with my name and asking her if she remembered me from the club, and if she was still working, and where. I get an almost immediate response saying she did, and that she wasn't working at the moment, would I like to meet up. Since I had an all but confirmed "appointment" for no more than two hours hence, I deferred, saying that I wasn't prepared to do that right now, but how about next week sometime? Because of that "not now", I expected silence, but she asked me if I'd care to meet for drinks to discuss it and give her a chance to change my mind. Warning her that it wasn't likely, I said sure, and we arranged to meet at a local bar. (As an aside, let me just say that the bar we went to made some of the dive-iest strip clubs I've been to look like the bar at the Ritz by comparison.) We met, I bought her drink and a sandwich, we went to the back room (not like a VIP, just the rear most "dining" room of the bar), and talked for a while about what we might do, what kind of value we might each provide, etc, etc. I reiterated my earlier statement that I wasn't prepared to do anything tonight, but if things changed, I'd let her know. I gave her the change from the bar bill, about $15, and we parted ways on what I thought was a good note. Fast forward a half-hour or so, and I get another text from K asking me if I was still planning on going to the club, to which I replied that I was. Then she asked me for a ride to work, saying her roommate was all upset about something and she was being all bitchy. We back and forth for a couple of minutes, with me asking where she lived, what time she wanted me to pick her up and all that. Suddenly... I get this from J: "Why you texting my roommate? Lose my fucking number, asshole. You cheap ass bastard. What the fuck was 15 bucks?" Hmmmmm. So I texted J back, and asked who her roommate was. The only response I got was a repeat of "Lose my number, asshole." So I asked K if she had a roommate, and if she matched the description of J. The response is affirmative. Me: Is she bitching about some guy who she met and "only" gave her $15? K: Yeah, why? Me: I think that tonight would not be a good night for me to get between two roommates. She's talking about me. K: ??? Me: A brief explanation, along with a promise to meet her in a ocuple of days, if she still wants. Fortunately, it has since worked out OK, with both of them. Surprise, surprise, money was all it took to get back in J's good graces, and K thought the whole thing was funny as hell. Unfortunately, neither of them really turned out to be my thing in the long run.
