Salesman upset over censure (7)
I believe the answer is:
reprove
'censure' is the definition.
(thesaurus)
'salesman upset over' is the wordplay.
'salesman' becomes 'rep' (sales representative).
'upset' indicates an anagram.
'over' anagrammed gives 'rove'.
'rep'+'rove'='REPROVE'
(Other definitions for reprove that I've seen before include "carpet" , "tick off" , "Admonish" , "Scold" , "Criticise" .)
