Minnow, 99.9% of the time I am seemingly a very nice guy and don't get phased by much of anything. However, in the rare instances where a dancer screws around while I am being entertained by another dancer, I go into asshole mode real quick. I have a zero tolerance for this type of behavior. I would have told M that I'd dance with whoever the fuck I wanted to.
That may sound like tough talk, but I practice what I preach. I learned, through some hard lessons in my younger years, that pushy or desperate dancers can ruin your entire night if you let them. If you don't control your space/experience, someone else will, especially in high hustle clubs. I keep my proverbial newspaper rolled up in my back pocket, ready to use on the noses of aggressive dancers who try to pull stunts just like that.
With respect to E2, I probably would have thanked her for stopping by and then told her that I'm not looking for company at the moment. I would have sent her away with a smile, but also a firm look (one I use often to send away dancers who don't take a hint). Then, when E1 was done on stage, I would have invited her over. E2's offense wasn't quite as egregious since E1 was on stage as opposed to the seat next to you, but she knew what she was doing.
Now I'll be perfectly candid in saying that I struggle with this a lot more when it involves girls with whom I have engaged in OTC p4p, especially when I don't want to lose them as a source. In fact, I've written volumes in the blue side about those struggles. But in ordinary club situations, I will never let a dancer interfere with my interactions with other dancers.
Anyway, just my
