Smile more excitedly as one delivers drinks (9)
I believe the answer is:
sommelier
'one delivers drinks' is the definition.
I can't tell whether this defines the answer.
'smile more excitedly' is the wordplay.
'excitedly' is an anagram indicator.
'smile'+'more'='smilemore'
'smilemore' is an anagram of 'SOMMELIER'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for sommelier that I've seen before include "One removes a capsule before opening" , "Wine waiter" , "Restaurant worker" , "Wine steward" , "Expert" .)
