Complaint, getting boot for dish (4,10)
I believe the answer is:
beef wellington
'dish' is the definition.
(beef Wellington is a kind of dish)
'complaint getting boot' is the wordplay.
'complaint' becomes 'beef' (beef can mean a complaint or objection).
'getting' is a charade indicator (letters next to each other).
'boot' becomes 'Wellington' (Wellington boots are a type of boot).
'beef'+'wellington'='BEEF WELLINGTON'
'for' acts as a link.
(Other definitions for beef wellington that I've seen before include "Menu item" , "dish - with 10a" , "meal" , "Meat-in-pastry dish" , "meat dish" .)
