Express delivery part of its service? (5,5)
I believe the answer is:
paper round
'express delivery' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'part of its service?' is the wordplay.
I cannot quite see how this works, but
'part' could be 'pap' (pap is a kind of part) and 'pap' is found within the answer.
'of' could be 'o' and 'o' is found in the answer.
'service?' could be 'run' (servicing is a kind of running) and 'run' is located in the leftover letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for paper round that I've seen is " It'll earn a little".)
