The Catering Corps? (6,7)
I believe the answer is:
dinner service
'the catering corps?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for dinner service that I've seen before include "Set" , "Plates and dishes for complete meal" , "Plates, dishes, etc" , "Crockery for meal" .)
