A quick check Is generally ok. It lets you see if they're degenerates and catch some red flags before you waste time/money on going out with her. Absolutely nothing more than that however. Besides the fact that it's going to destroy you coming off natural, it's just way too much energy dedicated to the girl at that point. After all, you've got her or are about to get her on a date, why do you care about anything farther than just obvious red flags? At best it'll only be a waste of your time: at worst it'll make you far more invested and nervous than you need to be.
