Well, they are non-obvious slots near Flight Attendant stations and high traffic areas. I wont say I hung out near them on a flight and observed traffic patterns, nor did I observe periods in the rear of the plane where one CF slot was unattended. I forget the exact model now, but Im leaving out alot of detail. There are assumptions in the "unattended slot" hypothesis. For one, the slots need to be set to an autoplay, which is not a given, and if not- requires navigating a complex and dated touch screen.
