I've been watching Orange is the new Black lately, and the Con-Air scene was pretty similar to their description. Sounds like it's true that you really don't want to use the bathroom there, doubly so if you're a girl. And that they really don't want to take your cuffs off for any reason. And the guards all act like everybody there is planning to pull a Con-Air movie style hijacking, and so will not tell you anything or talk in any way that isn't strictly required.
