Regular patron (7)
I believe the answer is:
habitue
'regular patron' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for habitue that I've seen before include "One who visits a place frequently 97)" , "Frequent visitor to a place" , "Person who visits a place frequently, may live there" , "Constant visitor" , "Regular customer" .)
