They get what's coming to them (6)
I believe the answer is:
payees
'they' is the definition.
Both the definition and answer are plural nouns.
Perhaps they are linked in a way I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for payees that I've seen before include "The people who receive the money" , "Cheques are made out to them" , "Those who get the money as for goods or services" , "To whom money is paid" .)
