Demanding some coffee (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
instant
I believe this clue is a double definition.
'demanding' is the first definition.
(thesaurus)
'some coffee' is the second definition.
(instant coffee)
(Other definitions for instant that I've seen before include "Sort of coffee" , "Short time; immediate" , "Immediate, twinkling" , "Fast, flash" , "Tick" .)
