Use roughly half of normal free entertainment (8)

I believe the answer is:

maltreat

'use roughly' is the definition.
(I've seen this before)

'half of normal free entertainment' is the wordplay.
'half of' indicates taking half.
'free entertainment' becomes 'treat' (I've seen this before).
'normal' with half the letters taken is 'mal'.
'mal'+'treat'='MALTREAT'

(Other definitions for maltreat that I've seen before include "Behave badly towards on late tram" , "Ill-use" , "Use roughly" , "Harm" , "Act badly or cruelly towards someone" .)

I've seen this clue in The Times.
