Umm Ladies night does not bar men. It offers women drinks for less. It isn’t just ladies who can go. I used to know guys who went on Ladies Night to pick up girls.
I used to know guys who went on Ladies Night to pick up girls. That is precisely the point of Ladies' Night. I would guess it typically results in more women than an average night, which of course will bring in more guys. Works out for everyone.
Jack's got a good point though. Instead of "whites only" night, think "Whites' Night". Discount for whitey. While stupid, it should be no less legal than Ladies' Night.
It offers women drinks for less. Prices for whites: $X
Prices for blacks: $Y
How long do you think THAT establishment would stay open?
