Good tips on those links I liked them. I will share one since it seems many of us are in the same boat here - At my college, our cafeteria is in the student union building which is our student "hang out" place but not really since it kinda sucks.
Anyways I usually go get lunch there, and after getting my lunch I eye the place down a little bit for girls sitting alone, then once I find one ill go over there and pull out a chair, and ask "is anyone sitting here?" most of the time they say no, go ahead & sit down. Sometimes they are waiting for friends but still say sit - havent been rejected on this approach yet - I expect to get some once I try it on doubles.
Anyways once you sit down there with her you can talk to her about whatever you please - most the time I say that smells good what they are eating & ask what is then fluff about that for a minute then try to steer the conversation towards her, such as her major, what does she do, is she in a soroity, blah blah. Then once you feel you can get her #, look at your cell phone, or watch then say you need to go but it was nice talking to her. I'll usually say you seem pretty cool we should hang out sometime give me your number, I still find my self choking on asking for their # about 1/4 of the time, or if the convo wasnt that great.
If they drink alchol ill talk to her bars/alchol then try and get her to go out that night if possible. SO far doing that, iv had several flake and 1 actually end up going out that night. Anyways that's my little lunch time tip - I hope some of you use it and have much success!
