Service area for butcher (8)
I believe the answer is:
massacre
'butcher' is the definition.
(thesaurus)
'service area' is the wordplay.
'service' becomes 'mass' (I've seen this in other clues).
'area' becomes 'acre' (I've seen this before).
'mass'+'acre'='MASSACRE'
'for' is the link.
(Other definitions for massacre that I've seen before include "Indiscriminate slaughter" , "Slaughter, pogrom" , "Butchery" , "Destroy" , "Large-scale indiscriminate killing" .)
