Many books advocate turning down a last-minute date request, with the premise that it makes the person accepting the date look "desperate." While you don't want to be a "sure thing" every time he calls, it's totally fine to accept a date at the last minute if you want to go. When it comes to ordering food, many dating guides advocate ordering the stereotypical salad or other light dish. But you should feel free to order what you want - within reason. If someone else is paying for your meal, it's polite to stay in the price range of whatever he or she is ordering. Don't get caught up in the "calculations" and accepted timelines of dating - that includes waiting to call or contact your date, money matters, or having sex. The truth is, there's no magic formula, game, code, book or whatever the "relationship gurus" call it for a successful relationship.
