Fellow consumer? (8)
I believe the answer is:
cannibal
'fellow consumer?' is the definition.
(I've seen this before)
'fellow' is the wordplay.
I cannot quite see how this works, but
'fellow' could be 'al' (I've seen this in other clues) and 'al' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cannibal that I've seen before include "One who eats its own species" , "Person eating human flesh" , "Person who has someone for dinner?" , "Eater of one's own kind" , "Person who eats human flesh" .)
