More polite with agent (3)

I believe the answer is:

rep

'agent' is the definition.
(short for representative)

'more polite with' is the wordplay.
'with' says the answer is hidden in the clue.
'REP' can be found hidden inside 'more polite'.

(Other definitions for rep that I've seen before include "Theatre; fabric; salesman" , "agent" , "Salesperson" , "Representative; fabric" , "Stuff" .)

I've seen this clue in The Mirror.
