Upset about work, drinks (5)

I believe the answer is:

topes

'drinks' is the definition.
('tope' can be a synonym of 'drink')

'upset about work' is the wordplay.
'upset' becomes 'tes' (I've seen this in other clues**).
'about' means one lot of letters goes inside another.
'work' becomes 'op' (abbreviation for opus).
'tes' enclosing 'op' is 'TOPES'.

I've seen this clue in The Telegraph.
