CrazyMonkey, I have to warn you that female bartenders are notoriously skittish when it comes to their male customers. (I am one. Take my word for it. :D) So for those of you wondering why she ran off and didn’t come back…well, I can totally see doing that, b/c obviously Evil Girl made her feel uncomfortable. It’s like, “Oh, wait, this is some girlfriend of his, or some psycho customer, and I don’t want to be a part of some drunk dramatics.”
The other thing you unfortunately have to consider is that she was just being polite by talking to you, and that she considered Evil Girl to be her guiltless ticket out of there. (I have had customers approach me when I get off work, and I’m never reluctant to talk to them, b/c I’m still at work–even though I’m off the clock–but that doesn’t mean I’m actually interested. I just think it’s cheesy to “make friends” with customers when I’m working, and then totally blow them off when I’m not. Kind of ruins the whole facade. I want them to come back tomorrow and tip me again. ;))
However, let’s assume that you did stand a chance with her; let’s assume that Evil Girl just made her uncomfortable. (She doesn’t know, after all, that EG is an ex of yours. And a lot of guys, believe it or not, will blow off the date they showed up with if they think they stand a chance with some other girl. I’ve had guys ask me for my number in front of their date, or when she’s in the restroom. So remember that Cute Bartender may be assuming the worst.)
I think it was poorly played that you enticed Evil Girl into your car and made out with her, just to kick her out; I see the temptation to do it, and I can taste the momentary satisfaction, but it was still poorly done. Revenge on a girl, even a horribly bitchy girl, is still not the behavior of a gentleman; it makes you just as manipulative as she is. But since what’s done is done, your best hope is that nobody from the bar saw you making out with her; let’s just hope that Cute Bartender doesn’t know. (Because regardless of what EG did, you’re gonna look like an asshole from a girl’s perspective. Making out with a girl as “revenge” isn’t gonna make you look any better than she does. Sorry, but them’s the breaks.)
So if I were you, I’d go back to the bar when CB is working, have a few drinks, and casually apologize for EG’s behavior. Something like, “Hey, sorry about that girl the other night! We went on a date once and it didn’t work out, but she’s still friends with my friends so we run into each other.” The trick is not to dog EG to CB at all; you can add with a smile, “Sometimes she gets a little drunk!” but that’s about it. This makes you look like a gentleman; CB will assume the rest. If you dog EG, CB’s going to think you’re overcompensating–kind of like when someone’s guilty, and they can’t shut up about how innocent they are. So just play it off and don’t keep talking about it. A casual apology will suffice.
And if that doesn’t work…well, you gave it your best shot!
