Why would you think that? I would consider my date worth my getting nicely dressed my being on a little more formal behavior until we knew each other better. I would expect the same of him.
Not everyone is made out of money. Would you rather that he take you to a fairly nice restaurant and use a coupon that cuts a $60 bill to $30, or would you rather he just spend $30 straight up by taking you to KFC?
What’s the priority here, the person you’re dating or his pocketbook?
