help a clueless guy about paying for dates

[NASCARFAN925]

ok first off i'm not some kind of an a$$hole. i'll pay for the first date and usually the 2nd too. but if the woman hasn't even offered to pay for anything by the 3rd date, do you just drop them outright? or do you somehow bring it up in conversation? if so, how do you bring it up? like i said i'm clueless and retarded so i'm gonna get that right out of the way.
