For sure, we are not supposed to judge. But it sure is hard when I read stories that Mark posted (tongue in cheek - humor).

Damn, bringing in a car full of $6000 worth of equipment for a handful of patrons, might be stupid. But that load only takes 15 minutes to set up. I cannot tell you how many people are marveled by the technology and the skill set that must be accomplished to satisfy and 'keep' the crowd. A performance is analyzed by how many people stay. Mark's example showed that listeners really do know, IMO.
