Overheard complaint initially about student that waiter brings? (4,4)
I believe the answer is:
wine list
'that waiter brings?' is the definition.
(a waiter might give you the wine list)
'overheard complaint initially about student' is the wordplay.
'overheard complaint' becomes 'wine' (I can't justify this - if you can you should give a lot more credence to this answer).
'initially' becomes 'ist' (ist resembles wst).
'about' is a charade indicator (letters next to each other).
'student' becomes 'l' (as in L-plates for learner drivers).
'ist' after 'l' is 'list'.
'wine'+'list'='WINE LIST'
Can you help me to learn more?
(Another definition for wine list that I've seen is " Drinks".)
