Take food from the attendant (3)
I believe the answer is:
eat
'take food' is the definition.
(to eat is to have some food)
'from the attendant' is the wordplay.
'from' indicates a hidden word.
'EAT' is hidden within 'the attendant'.
(Other definitions for eat that I've seen before include "put away" , "Corrode" , "Dine in a restaurant" , "Do cats - bats? Do bats - cats? (Alice in Wonderland)" , "Bit, chew and swallow" .)
