Crossword Genius

Close, around lunchtime, small joint (2,4,5)

Ross

I believe the answer is:

at ones elbow

I'm a little stuck... Click here to teach me more about this clue!

'close' is the definition.
(I've seen this before)

'lunchtime small joint' is the wordplay.
'lunchtime small' becomes 'atones' (I can't justify this - if you can you should believe this answer much more).
'joint' becomes 'elbow' (elbow is a kind of joint).
'atones'+'elbow'='AT ONES ELBOW'

'around' is the link.

Can you help me to learn more?

(Another definition for at ones elbow that I've seen is " close".)

I've seen this clue in The Times.
