Quick coffee? (7)
I believe the answer is:
instant
I believe this clue is a double definition.
'quick' is the first definition.
(thesaurus)
'coffee?' is the second definition.
(instant coffee)
(Other definitions for instant that I've seen before include "A second - coffee, maybe" , "Split second" , "Sudden; moment" , "This coffee is made from powder" , "like some coffee?" .)
