I was at the place until late, I left about 20 minutes before the fight. Supposedly the fight started inside the club, security bounced them, and a fight ensued. Not sure of the "issues" but I remember there was anger at the club.
It ruined an OTC encounter for me (I am pissed).
The next day, everything was fine.


Short version according to the Palm Beach Post: Two groups of guys were arguing exiting Cheetah and it spilled out into a fight in the Mattress City parking lot next door. A knife was pulled and the victim staggered back to the Cheetah parking lot. No arrests as of yet as the culprit fled the scene.
