Bishop constantly taking a long time getting drinks (9)
I believe the answer is:
beverages
'drinks' is the definition.
(I know this)
'bishop constantly taking a long time' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'constantly' becomes 'ever' (I've seen this before).
'taking' is a charade indicator (letters next to each other).
'a long time' becomes 'ages' (ages can mean a very long time).
'b'+'ever'+'ages'='BEVERAGES'
'getting' is the link.
(Other definitions for beverages that I've seen before include "Vegas beer (anag) - beer etc" , "Drinks" .)
