I don't have anything against "Where are you from, come here often" but they don't help you either. If anything they're inefficient and come off as boring/typical. If I don't have anything to say I ask for qualifiers. Something like "You look friendly (fun), are you friendly (fun)?" but in a playful, suspicious way, just to boost attraction early on. This communicates that you have standards, as little as it is, so always have that suspicious smirk and almost your words don't matter.
I just watched Brad Barnson talk about tonality. By the way if you don't know this guy YouTube him. He's got great stuff on tonality and voice. To a point where you rarely have to worry about your words as much.
Here's a great video:
