How good client pays in an hotel possibly (2,3,4)
I believe the answer is:
on the nail
'how good client pays' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'in an hotel possibly' is the wordplay.
'possibly' indicates an anagram.
'in'+'an'+'hotel'='inanhotel'
'inanhotel' is an anagram of 'ON THE NAIL'.
Can you help me to learn more?
(Other definitions for on the nail that I've seen before include "Exactly" , "location of solution for digital protection" , "Prompt" , "focus of manicurist?" , "immediately" .)
