Suitable extra task for a delivery driver? (7)
I believe the answer is:
fitting
I believe this is a double definition.
'suitable' is the first definition.
(synonyms)
'extra task for a delivery driver?' is the second definition.
(eg someone delivering furniture might fit it too)
(Other definitions for fitting that I've seen before include "Appropriate, proper" , "reason for appointment with tailor" , "Seemly" , "Suitable, proper" , "Apt" .)
