Spread measures of drink for one who can't hold it? (6,7)

I believe the answer is:

butter fingers

'one who can't hold it?' is the definition.
(term for someone who easily drops things)

'spread measures of drink' is the wordplay.
'spread' becomes 'butter' (I've seen this before).
'measures of drink' becomes 'fingers' (a finger is a small amount of alcohol).
'butter'+'fingers'='BUTTER-FINGERS'

'for' acts as a link.

I've seen this clue in The Guardian.
