I have seen advice from famous writers that cliches should be avoided. It seem like pretty hard advice to follow.
What is the difference anyway, between an 'everyday idiomatic expression' and a 'tired and boring old cliche'?
Do you prefer simple literal language over something that may appear unoriginal?
My feeling is that a cliche used in an unusual enough situation makes the writing (the idea being expressed) original, at least original enough.
