Old fool limiting current place for refreshment (5)

I believe the answer is:

oasis

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

'place for refreshment' is the definition.
'oasis' can be an answer for 'place' (I have seen 'Place of refreshment ' mean 'oasis' so perhaps 'place' could also mean 'oasis'). I am unsure of the 'for refreshment' bit.

'old fool limiting current' is the wordplay.
'old' becomes 'o' (abbreviation).
'fool' becomes 'ass' (both can mean a stupid person).
'limiting' indicates putting letters inside.
'current' becomes 'I' (symbol for electric current).
'ass' placed around 'i' is 'asis'.
'o'+'asis'='OASIS'

Can you help me to learn more?

(Other definitions for oasis that I've seen before include "Peaceful area away from trouble" , "can provide welcome relief" , "Fertile patch in a desert" , "Peaceful spot" , "where palms grow" .)
