Business fury involving one thousand fee added to drinks bill (7)
I believe the answer is:
corkage
'fee added to drinks bill' is the definition.
I can't tell whether this definition defines the answer.
'business fury involving one thousand' is the wordplay.
'business' becomes 'co' (short for company).
'fury' becomes 'rage' (synonyms).
'involving' is an insertion indicator.
'one thousand' becomes 'K' (synonyms).
'rage' enclosing 'k' is 'rkage'.
'co'+'rkage'='CORKAGE'
Can you help me to learn more?
(Other definitions for corkage that I've seen before include "Fee charged by restaurants for serving wine brought by customers" , "Charge for bringing own wine to restaurant" , "Restaurant's charge for bringing own wine" .)
