See you for beer, G&T exchange? (5)
I believe the answer is:
later
'see you' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for later that I've seen before include "At a time in the future" , "More recent" , "Eventually" , "Alert (anag.)" , "At a subsequent time" .)
