A judge in New Jersey has ruled that "ladies night" promotions, wherein women get cheaper drinks or a reduced cover charge, are discriminatory against men, and therefore illegal. As Jakeneck observes, many of the male barhoppers now freed from this insidious discrimination may not appreciate it all that much.
Interesting to see the piece's account of the legal reasoning that's allowed such promotions to stand in other states, though:
Judges in Pennsylvania and Iowa have said similar events are illegal, but courts in Illinois and Washington state have said that ladies nights are permissible because they do not discriminate against men but rather encourage women to attend.
That, of course, doesn't make any sense either, since a method of encouraging women to attend can (and, insofar as its targeted at women, would almost have to) also be discriminatory.
