Producers routinely come down on suitcasers in Stalinesque fashion.
One producer calls them bottom-feeders "mooching off everyone else who has spent marketing dollars to be at the show."
But suitcasers may not see themselves as mooching, doing damage to their own reputations, or even harming the event.
One suitcaser in fact told Levere he was an evangelist. "I think I’m adding value by spreading the word," he said. "A lot of people most likely attended the conference because I mentioned it.”
