Return motel menu that’s dreadful (9)
I believe the answer is:
emolument
'return' is the definition.
(an emolument is a financial return)
'motel menu that's dreadful' is the wordplay.
'that's dreadful' indicates anagramming the letters.
'motel'+'menu'='motelmenu'
'motelmenu' is an anagram of 'EMOLUMENT'.
(Other definitions for emolument that I've seen before include "Compensation paid" , "profit results" , "payment" , "Profit of employment" , "A fee received, salary" .)
