"That's right shoppers, this fantastic collection of Robio Donnahue memorabilia could be yours..."But since some other people prefer delusion to the truth, should the robot ask the person before answering?

KRYTEN: Are you of the school that, when faced with bad news, prefers to hear that news naked and unvarnished, or are you of the ilk that prefers to live in happy and blissful ignorance of the nightmare you're facing.
RIMMER: Ignorance, every time.
KRYTEN: (Very cheerily) Congratulations sir! You've come storming through your medical with flying colours. See you next time.
RIMMER: Everything's OK then?
KRYTEN: Absolutely peachy.
RIMMER: I want to know, Kryten, if there's something wrong.
KRYTEN: If there were something wrong, sir, I would tell you.
RIMMER: Even if I'd asked you not to?
KRYTEN: Well no. In that case I would lie and tell you everything was absolutely peachy.
RIMMER: Kryten, I want to know, that's why I asked for a medical. Is there bad news?
KRYTEN: Lie mode cancel. Yes sir, I'm afraid there is.
