This is standard. Tikki lays the Kang on the table, then submits to a quick 
frisk. Duke grunts, then jabs with a horny, lumpy knuckle at a button on the 
inside wall. A buzzer sounds. The slit in the inside door flips open, but 
several moments pass before the door swings open. Some people never get through 
that door. You have to know the right name. You have to be considered safe.
