Club's bill rejected (3)
I believe the answer is:
bat
'club's' is the definition.
(bat is a kind of club)
'bill rejected' is the wordplay.
'bill' becomes 'tab' (tab is a kind of bill).
'rejected' shows that the letters should be reversed in order.
'tab' reversed gives 'BAT'.
(Other definitions for bat that I've seen before include "Creature" , "Flutter (eyelids)" , "Small flying mammal, may be vampire" , "Nocturnal flier" , "Night-flyer" .)
