A woman that doesn't open the door for her date is a princess who wants to be pampered. Put down the fairy tale and step back into the real world. Do not order the most expensive thing on the menu. This isn't your birthday, and I am not your grandpa. We are college students with tight budgets for Christ's sake.
Most guys consider that adding on a few extra toppings constitutes an upscale meal.
Always reach for the check when it comes. The ultimate turn-off for guys is a woman who will not shut up. This is vital. Just as opening the door shows your date that you respect him, the reach shows him that you do not appear to be a gold-digger. Men also have certain wants during the date.
