Steak gets a complaint (4)
I believe the answer is:
beef
'complaint' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for beef that I've seen before include "gripe" , "See 24" , "Muscle; meat; grievance" , "Brawn; complaint" , "Grouse - meat" .)
