Dessert was served as flight attendant was called (10)
I believe the answer is:
stewardess
'as flight attendant was called' is the definition.
(outdated term for a female flight attendant)
'dessert was served' is the wordplay.
'served' indicates an anagram.
'dessert'+'was'='dessertwas'
'dessertwas' with letters rearranged gives 'STEWARDESS'.
(Other definitions for stewardess that I've seen before include "Aircraft attendant" , "Female flight attendant" , "working woman" .)
