if you're talking to a girl, never take her out to a restaurant as the first "encounter"
i had a situation that could've become this a few months ago. had a pretty fine black girl give me her number. literally within a day of talking, she's suggesting me taking her out to eat.
red flag #1. 
compound that with the fact that even over text, she seemed very vapid and airheaded, i dodged the L by ghosting. she just hit me up again recently.
always see if a chick is down with a more low-key venue FIRST (e.g. - museum, coffee shop, park). if the conversation and vibe is good, then ask her out.
protect yourself and your wallet at all times
