Opening Lines for Chicks @ Coffee Shops

[Malachii]

I've been working on my game lately and trying gets numbers from chicks at coffee shops. While I'm not a ladies man like TT or whoever, I'm also not a shy guy. Starting up a conversation and not having it go anywhere doesn't really bother me. What I DO have a problem with is that first few seconds where I spot a chick I'm interested in... I can't think of anything to say, and by the time I come up with something I have a hard time "pulling the trigger" and going up to her. I'd like something that I can just say right away to get me into the flow of things.

What are some standard opening lines that fellow OOTers use in my situation? And please, no corny pick up lines, I'm looking for something that people actually use.
