Hang on: one way to get a tip? (4,3,2)

'hang on' is the definition.
(phrase used to tell someone to hang on or wait)

'one way to get a tip?' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
'way' could be 'w' (Compass direction - West) and 'w' is located in the answer.
'to' could be 'for' and 'for' is found within the answer.
'a' is found in the answer.
The remaining letters 'tit' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
