Case of archetypal sucker stopping to pay for "financial security" (4,6)
I believe the answer is:
meal ticket
'financial security' is the definition.
'case of archetypal sucker stopping to pay' is the wordplay.
I cannot really understand how this works, but
'sucker' could be 'tick' (I've seen this before) and 'tick' is found within the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for meal ticket that I've seen before include "It provides food" , "Luncheon voucher" , "sought by gold-digger?" .)
