Mismanaging slight income - lush’s last to leave when the pubs kick out (7,4)
I believe the answer is:
closing time
'kick out' is the definition.
The definition suggests a singular noun which matches the answer.
'mismanaging slight income lush's last to leave when the pubs' is the wordplay.
I cannot quite understand how this works, but
'last' could be 'closing' (similar in meaning) and 'closing' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for closing time that I've seen before include "when the pub shuts" , "End of (drinking) session" .)
