ok first,

just forget everything you learned on PUA or all that shit, this is daylight game, not some party or club where people are open to strangers approaching them, and if she is, I doubt you want to blow your only chance finding out.

this works,trust me, for peeps who are skeptical, you either did not deliver it with enough confidence, correct tone, good posture, eye contact, or that girl was just having a bad day. Girls in Malaysia are not usually approached in daylight by men, for the very reason that most men are afraid. So doing so, will show that you are in fact an alpha among all those other men and even if she DOES reject you, would you rather her having remember you as that unknown stranger at the store or that confident guy who grabbed opportunity when it came but just wasn't her type? I propose the latter.

go up to her slowly in a 45 degree angle from to her (not from the back-stalker or front-might be too intimidating)

eye contact FIRST, then smile.

"I don't mean to be rude, but I just think you are an amazingly beautiful person and decided to come over here to introduce myself"

Tell your name, shake hands, ask hers.

"So I gotta run soon, but I'm getting a friendly vibe from you, could I have your number and call you out sometime?"

props to Mystery for this, this sentence does two things: 1) false time constraint-avoids and awkward silence and shows you are not lifeless 2)you said she was friendly,,now a friendly girl would not reject an invitation cause that would make her....??? yes, unfriendly. So she won't want that image.

That's all,simple and beautiful. Used it tons of times in malls,clubs,bars,college. Even on a bad day, success rate is 1 number out of 4 approaches. Which is pretty good considering most guys don't approach even one. So carpe deim, seize the day,life is short and you're gonna be a fertilizer soon, so what if you get embarassed? so what if you rejected? you're gonna die anyway,,that's worst. get everything you can out of this earth and make a change in your life. No exceptions.
