The Pandora's Box Auction House was set up like a large amphitheater with some private rooms established just above the seats. In total it had enough space to house 50,000 people, with exactly 50 VIP rooms that were capable of holding up to 5 people each.
The place was soon filled to the point where some people had to stand. The auction house was not open-air but rather an indoor stage with a large, cavern-like space, so it was impossible to allow everyone to spectate.
As such, the Guard Androids went around verifying how much a person had in terms of Supreme Coins. Those who had little or none were evicted in favor of those who had more, as those were likely bidders.
The Guard Androids explained this fact to everyone, so the logic was clear. It was a solid business decision, but it was no different from telling someone that they would have to vacate a certain flight for another due to overloading or something similar.
