He sees I get the order for drink I put in (6)
I believe the answer is:
waiter
'he' is the definition.
'i get the order for drink i put in' is the wordplay.
I cannot quite see how this works, but
'i' could be 'a' and 'a' is located in the answer.
'drink' could be 'it' and 'it' is present in the answer.
This explanation may well be incorrect...
'sees' acts as a link.
Can you help me to learn more?
(Other definitions for waiter that I've seen before include "Estragon or Vladimir, for example" , "Table server" , "Server in restaurant" , "Attendant" , "Restaurant worker" .)
