Salesman to consume parrot (6)
I believe the answer is:
repeat
'parrot' is the definition.
(I've seen this in another clue)
'salesman to consume' is the wordplay.
'salesman' becomes 'rep' (sales representative).
'to consume' becomes 'eat' (eating is a kind of consuming).
'rep'+'eat'='REPEAT'
(Other definitions for repeat that I've seen before include "Say or perform again" , "Go over" , "No new programme" , "Quote from memory" , "Further airing" .)
