Afternoon drink and minutes with actor, one who cooperates (4,6)
I believe the answer is:
team player
'one who cooperates' is the definition.
(I know this)
'afternoon drink and minutes with actor' is the wordplay.
'afternoon drink' becomes 'tea' (I've seen this before).
'and' is a charade indicator (letters next to each other).
'minutes' becomes 'm' (common abbreviation).
'with' means one lot of letters go next to another.
'actor' becomes 'player' (synonyms).
'tea'+'m'+'player'='TEAM PLAYER'
(Other definitions for team player that I've seen before include "not a man without side?" , "One working well with colleagues" , "Cooperative type" , "One who works well with others" .)
