Difficult request: a bit of buttered roll? A toastie’s offered up (4,5)
I believe the answer is:
tall order
'difficult request' is the definition.
'tall order' can be an answer for 'request' (I have seen 'unreasonable request' mean 'tall order' so perhaps 'request' could also mean 'tall order'). I'm not certain of the 'difficult' bit.
'a bit of buttered roll? a toastie's offered up' is the wordplay.
'a bit of' says the answer is hidden in the clue.
'offered up' shows that the letters should be reversed in order.
'redrollat' is hidden within 'buttered roll a toastie'.
'redrollat' reversed gives 'TALL ORDER'.
Can you help me to learn more?
(Other definitions for tall order that I've seen before include "Demand to tax" , "Challenge" , "hard to fulfil?" , "Difficult demand" , "delivery of sequoias?" .)
