So I am relatively new to this community and "the game." I have been looking at most of the posts, and have been working on my approaching of women, I am currently at the point of being able to suck it up and approach most sets and talk to group. Almost all of my approaching is during the day (I attend college).

My sticking point is that when I am talking to a girl who I want to escalate with, then to eventually number close, I don't really know any good strategies to get her number. Other than just straight up asking for it, and in most convo's it just seems out of the blue.

Could i get some advice on how to number close, especially quickly for situations where i don't have much time (waiting in line) and such?
