What Does the Winner of the Belinda Blinked Tombola Actually Get?

The tall man running the tombola with Sir James tells the room that the prize is a real person. The highest bidder for each of the three women gets her as a servant for twelve hours and may take her home. There is one rule. A safe word, once spoken, stops the task and releases her from the twelve hours. The hosts say they have been to plenty of tombolas and none of them involved a safe word. The catch is that the servant must match the bidder's donation to the charity in order to have that safe word. The event is framed as a fundraiser. The prize is twelve hours of a person, not a bottle of lotion.
