Blew a fuse after golf, that's allowed (7)
I believe the answer is:
granted
'allowed' is the definition.
('grant' can be a synonym of 'allow')
'blew a fuse after golf' is the wordplay.
'blew a fuse' becomes 'ranted' (I've seen this in another clue).
'after' is a charade indicator (letters next to each other).
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'ranted' after 'g' is 'GRANTED'.
'that's' acts as a link.
(Other definitions for granted that I've seen before include "Conceded" , "One doesn't like being taken for it" , "OK - allowed" , "Admittedly; gave formally" , "Admitted" .)
