Think of it, a Hooters style restaurant where at the end of the meal you can make an arrangement with the manager to buy the waitress. The waitresses are completely unaware they could be sold, they are just happy with their pay. If sold, they are summoned to the manager's (soundproof) office where they buyer is responsible for subduing the waitress and arranging delivery.
Who's in? I'd buy the short latina pictured here. She'd make a fantastic pet.
