Two guests were put on the same seat. What happens?

It cannot happen. A seat holds one guest, and that rule lives in the database, not the screen. When two people seat someone on the same chair in the same moment, the first move stands and the second is refused with a note that the seat was just taken.

The person whose move was refused sees the guest back in the unseated list and picks another seat. Nothing needs to be cleaned up afterwards.
