Take food from tea trolley (3)
I believe the answer is:
eat
'take food' is the definition.
(I've seen this before)
'from tea trolley' is the wordplay.
'from' indicates the answer is hidden within the clue.
'EAT' can be found hidden inside 'tea trolley'.
(Other definitions for eat that I've seen before include "Make food disappear" , "Ingest" , "Have 23d [MEAL]" , "Corrode" , "Gobble up" .)
