A man who shows up on time is perceived as a very needy man. Needy is not good. You might be in a serious drought and really be very needy, but that still doesn't mean you have to look and act the part. You show up for a movie date at the predetermined time, and she is in the middle of fixing her hair and trying on 18 different outfits. The guy ends up sitting on the couch like a schmuck, thumbing through her Cosmopolitan magazines while making small talk with her giggling roommates.
Punctuality is suicide.
Drive around the block. Open his car door from the inside. Nowadays, chivalry works both ways under the moniker of mutual respect. If he cares enough about you to open the door for you, then you should return the favor. A woman that doesn't open the door for her date is a princess who wants to be pampered.
