Hello,
I need a piece of advice. There is this girl that works as a security girl in a club. She's very beautiful... I generally see her but I haven't still approached because I don't want to spoil the occasion. This situation creates 2 problems to me:

1 the fact that she's a security girl puts her in a superior position both because of her job and because I can be just one of the hundred guys in the club to her, and it's more difficult to be confident for me (also because she is very beautiful).

2 I think a different approach is needed, since a lot of guys talk to her so I need to stand out!

I thought to approach like this, but wanted your opinion before giving it a try: "Hey, hi there... There are a lot of girls on the dancefloor but I was struck with none of them. I think you're very beautiful instead...."

And what if she says "no"? I don't want to give up and go away.
The good point is that she generally is friendly and smile when people speak with her

First of all, if you're not going to talk to her with confidence might as well not even bother. Who cares if dozens of guys talk to her every night? Think of yourself as the quality above the quantity. If you don't think you're worth her time you won't be it. Even if you reharse good lines and what not it won't matter because you don't feel confident enough to talk to her.

Now, i'm super newb, so take it as a grain of salt if you want, but i would try to go and start a more conventional conversation with her. It can be about the club, ask her how many drunk guys she had to take out or something along those lines, what kind of people she meets there, etc etc. Don't boil down the whole thing to a "yes/no" quizz test. Others here will probably recommend you good routines, but again, if you're not confident enough trying something too complicated and complex would be a bad idea. Besides, she has probably heard all kinds of weird and silly openers, maybe a more regular conversation would be the right way to approach her.

i agree with the previous reply.. just build comfort and rapport, but stay out of the friend zone..after a while ull eventually b able to ask her when she leaves and if she leaves with anyone..that way u can c each other outside
