Crazy one is come to cut services (9)
I believe the answer is:
economise
'cut services' is the definition.
(I've seen this before)
'crazy one is come' is the wordplay.
'crazy' is an anagram indicator.
'one'+'is'+'come'='oneiscome'
'oneiscome' anagrammed gives 'ECONOMISE'.
'to' is the link.
(Other definitions for economise that I've seen before include "cut services" , "budget" , "cut costs" , "Scrimp" , "make cuts" .)
