Any advice is welcome in this opener, i've been using it for a year or two and i'm still working on it. It takes some skill to # close in 5 mins. I challenge you to try it yourself xD.
1. Ask for a cigarette
2. Stick around for the entire cigarette
3. Number Close before you finish the stoge (you have 5 mins tops, good luck)
Just a couple of tips, things i do/say:
"You know what, to be perfectly honest... I didn't need a cigarette, i have some of my own. I just thought you were really beautiful and i wanted an excuse to walk up and talk to you"
I try to keep conversation flowing, if it stops there's no chance you'll get her number.
As you're putting out the stoge, it's a perfect time to ask for her number - "well i really gotta get going, thanks for the stoge... oh and here, why don't you give me your number and we could meet for a coffee sometime and talk about x/y/z"(whatever the fark you had in common).
You can use this opener on groups or singles and it's very versatile, i love it . I pioneered this method when i was in arizona (sleeping on a farking couch) and very short on money, cigarettes and pussy.
