Ban hurting landlord, say (9)
I believe the answer is:
bartender
'landlord say' is the definition.
(I know that publican is a type of bartender)
'ban hurting' is the wordplay.
'ban' becomes 'bar' (I've seen this before).
'hurting' becomes 'tender' (synonyms).
'bar'+'tender'='BARTENDER'
(Other definitions for bartender that I've seen before include "One handling counter measures" , "server of drinks?" , "Local worker" , "The person doing the drinks" , "Landlord perhaps" .)
