Service held in various establishments (3)

I believe the answer is:

use

'service' is the definition.
(thesaurus)

'held in various establishments' is the wordplay.
'held in' indicates a hidden word.
'USE' can be found hidden inside 'various establishments'.

(Other definitions for use that I've seen before include "exercise" , "Practise" , "Apply, employ" , "Operate" , "Function, purpose" .)

I've seen this clue in The Telegraph.
