Out to lunch, do prefer concession made on course (4,4)

I believe the answer is:

free drop

'concession made on course' is the definition.
(golf term)

'out to lunch do prefer' is the wordplay.
'out to lunch' is an anagram indicator (out to lunch can mean mad).
'do'+'prefer'='doprefer'
'doprefer' is an anagram of 'FREE DROP'.

(Another definition for free drop that I've seen is " Concession to golfer, perhaps".)

I've seen this clue in The Times.
