Consumes when tea's served out (4)
I believe the answer is:
eats
'consumes' is the definition.
(eating is a kind of consuming)
'tea's served out' is the wordplay.
'tea's' can be anagrammed to 'EATS'.
Though, I am not clear how this is indicated.
'when' is the link.
Can you help me to learn more?
(Other definitions for eats that I've seen before include "meal" , "Devours - food" , "Ingests" , "Is not any faster" , "Swallows food" .)
