For others' benefit, saloon's opening without Sprite? (10)

'for others' benefit' is the definition.
(thinking of others rather than oneself)

'saloon's opening without sprite?' is the wordplay.
I cannot really see how this works, but
'without' could be 'less' (I've seen this in another clue) and 'less' is present in the answer.
'opening' could be 'fly' (fly is a kind of opening) and 'fly' is located in the leftover letters.
The remaining letters 'sel' 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).
