Here's a suggestion for a "fire mission" by those that live/work in that area . . .
A number of NES'rs should go there, take a tour, let them give you the sales pitch, then ask to speak to the manager . . .
Then tell the manager "you have a nice place here, I really would join, BUT I heard that you screwed some Veterans who are currently serving in Iraq by billing them after they canceled. Sorry, I don't need the hassle of dealing with companies that try to take advantage of our Servicemen/women" and on that just turn on your heel and leave.
That'll really "bring it home" that they have screwed the pooch and people know about it.
Everyone who does this has to do it independently so they know that the word has spread widely. Doing it as a group won't have that impact.
