Beer's in demand to improve patient rapport (7,6)
I believe the answer is:
bedside manner
'patient rapport' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'beer's in demand to improve' is the wordplay.
'to improve' indicates an anagram.
'beers'+'in'+'demand'='beersindemand'
'beersindemand' with letters rearranged gives 'BEDSIDE MANNER'.
Can you help me to learn more?
(Other definitions for bedside manner that I've seen before include "Doctor's approach or attitude to a patient" , "Reassuring trait of doctor" , "Doctor's demeanour with patient" , "Doctor's way with patients" , "9 bearing" .)
