Nightclubs that advertise “ladies free” are actually using women as part of the experience they are selling to (heterosexual) men whom they perceive as their legitimate customers.  This is the reason men are expected to pay and “ladies” are admitted “free”. It is neither an act of feminist benevolence nor discrimination against men that club owners have such policies.  Such policies aid in heterosexualizing public spaces and reinforcing the notion that ALL women should be sexually available to men.
