An Easy Way to Get Phone Numbers from Women (Does It Work?)

I read this advice on Dating Support Center and wanted to see what you guys thought:
Here is an easy way to get phone numbers from women:

1) Flirt with her.
2) Build rapport.
3) Flirt some more.
4) Find something in common with her.
5) Suggest doing that something "in common" together.
(Important tip: Don't ask. Suggest!) Example: "We should do rock-climbing together some time.")
6) Watch her reaction.
7) If the reaction is good, ask for her number.

The key here is to be CASUAL. Imagine she's not someone you’re attracted to…like you're just meeting a friend.

You'll be amazed at how *easy* it is to get phone numbers once you have this "casual attitude" down!

Would this work on you? What's worked for you before?
