Court official with gratuities for office workers (8)
I believe the answer is:
tipstaff
'court official' is the definition.
(I've seen this before)
'gratuities for office workers' is the wordplay.
'gratuities' becomes 'tip' (a gratuity is a tip paid to a worker).
'for' means one lot of letters go next to another.
'office workers' becomes 'staff' (I've seen this before).
'tip'+'staff'='TIPSTAFF'
'with' is the link.
(Other definitions for tipstaff that I've seen before include "Pat's tiff with the judge" , "Bailiff" , "One authorised" , "Judge's personal assistant in court" , "Court official" .)
