I think the bar wants to get people together of similar interest. If people are responsible enough to own/ride bikes, they should be responsible enough to know how much they can drink to drive home safely, thats not the bars responsibility IMO. The owners of Club W are huge bike enthusiests and probably want to bring people in that have the same interests and provide other riders with the same experience. If your gonna go to this “bike blast” and get overly drunk and be a fuckin idiot and ride home, its prob just a matter of time before you crash anyways.
edit: and as for making money, Im sure they want to make as much money as possible without people crashing their bikes and driving home drunk.
