Wait here for food, money and some coke, possibly (5,4)
I believe the answer is:
bread line
'wait here' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'food money and some coke possibly' is the wordplay.
'food' becomes 'bread' (bread is a type of food).
'money' becomes 'l' (L can mean 'pounds').
'and' is a charade indicator (letters next to each other).
'some coke possibly' becomes 'ine' (I can't explain this - if you can you should believe this answer much more).
'bread'+'l'+'ine'='BREAD LINE'
'for' acts as a link.
Can you help me to learn more?
(Another definition for bread line that I've seen is " Subsistence level -- queue for food".)
