Waiters in line? (5)
I believe the answer is:
queue
This clue could be a double definition.
'waiters in' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'line?' is the second definition.
(queue is a kind of line)
Can you help me to learn more?
(Other definitions for queue that I've seen before include "Waiting list" , "Buyers' line" , "Stand in line" , "Line of waiters" , "orderly people?" .)
