Hard-working oil drillers do (7,4)
I believe the answer is:
deserve well
'hard-working oil drillers' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'do' is the wordplay.
I cannot really see how this works, but
'do' could be 'serve' (serving is a kind of doing) and 'serve' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
I've seen this clue in The Globe and Mail.
Want a hint initially instead of a full solution?
