Yeah, part of it was; should I just yell at them--they were moving across the gym (make me look like an ass maybe?), or go ask the front to have them re-rack (and that's being a pussy, so no).  I think next time (I hope to Christ no next time), I'll say something immediately after.  I've been known to escalate with people I have no respect for, so hope it doesn't go past that.
