After a few minutes, the auction members handed over the twenty items to their respective owners, with each group handing over the items in the order specified by the auction.
Contrary to what one might think, the first item to be delivered was not the first to be sold that night, but the last. Since the last items were usually more valuable, they were worth more. As a courtesy of the organization, these most valuable items were delivered first, giving their respective owners the chance to leave the auction house first.
However, this was not an efficient strategy in terms of security for the auction winners and only served to get the most valuable items to their new owners more quickly.
There was no way for the auction organization to protect its customers 100%. Other organizations have tried various strategies in the past to ensure the safety of their customers and to prevent post-auction fights or theft.
