There is nothing wrong with buying a girl a drink if you aren't doing it with the expectation that it will get you that much closer to having her drop the panties for you. If you can't even pay your rent, you might not be best off spending your hard earned cash for something that might net you nothing. But if it really isn't gonna put that much of a dent in your wallet, it doesn't mean you think you can't get ***** except by paying for it or any B.S. like that. If you have already established a connection with her, and have a good flirtation with her already, maybe you've danced with her a little, not necessarily grindin' on her ass, just having fun, or whatever, and you can tell she's feelin' you, she will very often think it demonstrates character that you're willing to do nice things for people you don't know. But I don't mind helping people out or extending nice gestures here and there, regardless who receives the benefit, as long as they haven't slighted me in any way, and most of my friends are the same way.
We like to have fun, we buy drinks for each other, we buy drinks for girls if we are already having enough fun with them, and they buy drinks for us too. Don't be a tightwad, unless you're F**kin broke or maybe you're the pimp. Whatever. I just met an easy 9 at the club friday night, we were having fun on the dance floor, she waved at me a few times as we passed each other through the club. The last time we passed I stopped her, asked her if she was leaving cuz she and her 3 hot friends seemed they might have been. She said no, she was going to the bar to get a drink. She had been paying for her drinks thus far in the night, so it wasn't like she expected me to buy her her drink, and I'm sure she was planning on buying it for herself. But I asked if she wanted me to get her drink anyways, and she said sure. Then her friend wanted one too, and she stuffed 4 bucks in the pocket of my jacket and asked me to get that too, I teased her and said I don't know, she said come on, please, I said only if you give me your number, she said I was already planning to, you didn't need to buy the drink for that, so I said Okay then, I guess I won't get either of you a drink after all, she knew I was teasing her and laughed and said noooo pleeeeaaase, and I warmheartedly replied Ohhh, OK, I guess so.
Then we chatted at the bar, she introduced me to her to amazon goddess friends, who seemed pleased to meet me as well. I chatted with them shortly, and then focused my attention back to HB at the bar, and she asked me if I wanted a piece of gum. I said sure, she put it between her lips for me to kiss out of her mouth. Later in the night, after giving me her cell, home, and work phone numbers (I called her work number and it was in fact the place she told me she worked at, but I won't call her until tonight, probably see if she's at work around 9, cuz she's a waitress), she pulled my fur-lined hood up over my head (which was hella sexy) and put her head in with mine and started making out with me. So apparently it didn't bother her that I had bought her a drink.
But I can see where it would backfire if one didn't know how to read attraction signals very well. If you're broke and can't afford it, don't do it. But put some positive energy towards putting yourself in a better position, and once you are, don't be to scroogish to spread a little goodwill. Unless of course you're a pimp, and the *****es be payin' you an' sheeeeeoooottt, hustla. Pay attention to what jakethesnake and Big Pappy are schoolin' as well and you'll be just fine. Just don't break the bank buyin' *****es beers, and make sure they buy you some too. Don't ask for it, just expect it.
