If anyone is struggling with 7 down "Peers own advanced retail food outlet (4,1,7,1) there is a printing error it should be 4,1,8...answer Have a Butchers
I saw this given elsewhere as (4,1,7'1) which would suggest HAVE A BUTCHER'S which is more correct as it is short for HAVE A BUTCHER'S HOOK, rhyming slang for HAVE A LOOK.
