As nobody has got this (or admitted to getting it) could there be an error in the letters? If you are going to make up something rather than leave it blank how about Always sup something for breakfast!
Might just put that in,grasscarp! I phoned the quiz setter earlier this evening and there's not a mistake in the letters, and she's got quite a few back with that answer correct so I suspect we are not being told this answer on AB. Ah well, back to the proverb books. Thanks anyway.
