Service chief? (4,6)
I believe the answer is:
head waiter
'service chief?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'chief?' is the wordplay.
I cannot quite see how this works, but
'chief?' could be 'head' ('head' can be a synonym of 'chief') and 'head' is present in the answer.
The remaining letters 'waiter' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for head waiter that I've seen is " Who may serve".)
