On GirlsAskGuys, I often read that men are just tired of paying for the dinner or the date costs. That makes sense. Why should the financial liability be assigned to men all the time? It's not that they always ask people out. Sometimes, men ask out women. Sometimes, men ask out other men. Sometimes, women ask out men. Sometimes, women ask out other women. To be fair, the inviter should always pay for the date costs (please seriously consider how much money you would have to spend for two or additional participants, in case an unexpected guest wants to tag along, as shown in the following Cyberchase For Real episode), and the invitee should always allow the inviter to pay for the costs (no arguing for that bill just to save face).
Ladies, if you ask out a guy, don't expect that the guy would have to pay for the cost or that you can split the cost. He is a guest; you are the host. The deal is on you. You asked him out, not the reverse. So, you should pay for the cost of the service. If you can't afford the date costs, then you shouldn't dine out or go out in the first place. Instead, you may prepare a nice home-cooked dinner for two and play board games afterwards.
