There are a lot bigger issues, like building sexual tension and attraction, establishing comfort and creating a connection, showing that you are fun and that she would be lucky to hang around with you and have fun with you. I see this in a lot of guys that spend so much time focused on the importance of a first impression, that they never get past it and into anything else. It's like continuously planning out what you're gonna do for the night and trying to make the perfect plans, instead of just going out and finding some fun, so you end up sitting at home all night and never having any real fun.

Good points Rye.. anyway, as is mentioned above, the girls are taking us out for drinks on Thursday, so need for the number right now. In this particular case because there already is attraction, I will get the number mid-late way throught the night as opposed to at the end of the night.

Though thinking about it I don't really think it will make a big difference.
