Long story short, I met a cool, interesting woman at a work-related function. She works for a different company, so there's no conflict there.
We had a good conversation. It was as flirty as it could have been under the circumstances. Now here's the dilemma: I can't think of any good way to ask her out. I couldn't have done it at the function, because it would have put her on the spot in front of coworkers. Even asking for her cell phone number there would have been weird. I do have her office phone # and work email. Knowing her work environment, me calling her up there and asking her out would probably be bad. The only thing I can think of is to ask her to get coffee via email, and I must admit I'm not in love with this option. It's pretty impersonal, and I'm a face to face kind of guy.
Ladies, how do you think I should ask her out?
