Although the auction house was holding an event in London today, the boss behind it was a local, and there was a rule that the invitation belonged exclusively to the recipient and could not be used by anyone else. Any attempt to impersonate and enter would result in disqualification.
On the other hand, if the invitation belonged to you, not only could you enter, but you could also bring up to three friends or family members, depending on the level of your invitation.
However, invitations were ranked, and the lowest one was an ordinary seat with only one place; a slightly better one was a VIP sofa seat that could accommodate about three people; and the higher one was the VIP section.
But this VIP section was not located in the main hall but had its private compartment. Finally, the best one was the royal box with only three compartments, specially used to receive high-ranking officials and leaders or the ultra-rich.
