I have been out of the dating scene for a while, but will give you some tips.
1. First date at an expensive restaurant is dumb. Do the coffee, which you can get out for less than 12 bucks if she never calls you back. Happy Hour also works, because if the date is going south, you can get drunk. Save the expensive date for like date 4 or 5. First couple should be casual.
2. Keep the mace talk to yourself until you know the chick is into you. Listen I would love to talk maces with you, but I don't want to bang you and you don't want to bang me. Well you might want to bang me, but since you took a chick out, I am going to assume you are straight. I am a comic book and Star Wars nerd, I did not bring that shit up to the wife until after the first month.
