Doing so, a rotter will get a drink and go without nothing (7)
I believe the answer is:
cadging
'without nothing' is the definition.
I can't judge whether this definition defines the answer.
'doing so a rotter will get a drink and' is the wordplay.
'doing so' becomes 'gig' (I am not sure about this - if you are sure you should believe this answer much more).
'a rotter' becomes 'cad' (a cad is a dishonourable person).
'will get' means one lot of letters go next to another.
'a drink' is an insertion indicator.
'and' becomes 'n' (common abbreviation for 'and').
'gig' put after 'cad' is 'cadgig'.
'cadgig' enclosing 'n' is 'CADGING'.
'go' is the link.
Can you help me to learn more?
I've seen this clue in the Evening Standard.
