The last time we were actually there -- about 22 months ago -- I did not see the sign. We were both 'parched' at the time and ordered our drinks, and just as I was wondering if the "ladies drink for free" promo still was in effect sure enough not five minutes later two couples probably in their early 40's came up to the bar on our left and the ladies sat on the bar stools while their husbands (or boyfriends) stood behind them. Off went their tops and 'on' started the drinks so that answered that. I turned to my wife and said "I can save $9 on that margarita if you join them" to which I got a firm stare and was reminded that we weren't on the beach anymore! We got done and went into the nearby casino for about an hour. When there was no more money left to lose, we went back for one last round and lo and behold the two couples hadn't moved. They had to be drinking a good hour and a half, so I left wondering just how much the bar lost on those two ladies! Another great St. Martin memory.
