A drink with the cleaning lady (4)
I believe the answer is:
char
This clue is a double definition.
'a drink' is the first definition.
(I've seen this before)
'the cleaning lady' is the second definition.
(synonyms)
'with' acts as a link.
(Other definitions for char that I've seen before include "way to make carbon" , "Blacken by burning" , "Perhaps overheat" , "tea > daily" , "House cleaner" .)
