Tickets for Waits' summer shows were limited to two per person but, in an effort to beat ticket touts, a valid I.D. (passport or driving licence) matching the name on the ticket was required to gain entry. Any concert-goer who did not have a valid I.D. or was found to be in possession of a ticket that had been resold – electronic scanners were employed – was not allowed in and did not get a refund.

The perpetrators took orders from ticket brokers, who were required to provide credit card numbers and account holder names in advance of a purchase so they could be programmed into the bot.
