Wait for the conversation to get to its climatic point ,whether that would be through making a deep connection, or making her laugh to the point of tears. You have to at that very moment, end the conversation!
And say:
“I’ve really enjoyed OUR conversation, but I’m being really rude here,because my friends are waiting for me”
This is will make it seem that she is the one who has been keeping you there from your friends; furthermore, it allows you to demonstrate that although you have enjoyed yourself you have other plans. (always keep your audience wanting more)
Its vital you pick that climatic point of the conversation carefully, as it is common for guys to go beyond that point. After that intense moment of connection there is inevitably a lull, which, might confirm the fact that your still strangers and her barriers might return.
Quite literally many guys “miss the boat” in this situation.
Next, look at your watch, as you get up from your seat/down your drink/gather your cigarette packet and lighter and say
“We should carry on with this another time”
“Should” is the key word here. It’s more effective than “Can I” or “it would be nice”
Get out your phone before she has a chance to respond and hand it to her; tell her to tap in her number. Do this before she has a chance to react or, time to think “Should I give my number to this stranger? I’ve only known him for a few minutes, what if he’s a weirdo? I cant believe he thinks he can get my number this easy etc etc”
You must ALSO say:
“Right, when you have done that make sure you put it under a nickname, I can tell a lot about someone by there self appointed nickname, you know, how creative they are etc…”
This is a major point to this technique; it covers 2 things at once
1. It distracts her from the act of actually passing on her details, as she will find the task much more entertaining (girls like this shit)
2. It will suggest that she has already accepted giving over her details (never underestimate the power of suggestion.)
Good sales people do this all the time. You go in the store to maybe buy an item you had in mind, notice the good sales person will not ask if you want to buy one, instead they will ask you how many you want. Making you believe you have already decided on it and now are in the process of worrying how many you actually need!

This is a great way to number close a woman; she can get cold feet about handing you her number, even if she likes you!

If its been a short and sweet encounter, she will be thinking “but I’ve only known
him for a few minutes”

Please don’t be tempted to think this yourself, going beyond that pinnacle point of an interaction can ruin your chances. Rather instead, use this little tip of setting the nickname task.

Remember when delivering the task, do so with absolute self-assurance that she will perform - give a cheeky smile but remain dominant. (As always when you are giving a task)
