Before you try excusing this behavior with whatever excuses you have, see if your excuse still stands after asking yourself this:
Why shouldn’t the girl open the car door for the guy?
Because it’s polite to hold a door open for someone. I sometimes hold the door open for my wife and sometimes she holds it open for me.
Got a problem with it? Does the Torah have a problem with it? Or is there some 614th mitzvah somewhere that says “Thou shalt only open your own door?”
