It is possible. I've done it before, but I also had some inside knowlege about the girl we had talked while she was getting me a coffee. Then the next time I went through the drive through gave my card to the guy at the drive through and told him to give it to so and so he did she called we went out, but I also made an impression 1st by being really nice at the drive through speaker saying please thank you complimenting her on her coffee making abilities (jokingly) she'd always draw hearts on my cup so after a little while of that I made my move.
Anyway hope that helps good luck!!
Don't get mad but I don't think that would be considered as a "one-shot" pick-up situation (or at least not what I had in mind). You've been flirting with her for a while before giving her your number versus you being upfront with your approach to the girl you haven't met yet and trying to take it up from there (although I'm glad things went well for you in the end).
