Is it acceptable for car maintenance workers to change your settings?

I just got my car back from maintenance (gave it in on Wednesday). ALL the radio channels had been changed to other stations, the AC was blasting and set on facing the person and their foot (it was originally set on the back mirror and i don’t use it in general since it wastes resources) and the gas was considerably lower. I can rationalize the change in gas level by thinking that maybe they needed to take it out for a test drive on the highway to make sure the new brakes are working fine etc. But living in Ohio (where it’s not that hot), is it REALLY acceptable to change all the radio stations and blast the AC? even if the person wanted to listen to some music while working on the car, do they need to change all stations or shouldn’t they have set it back to the normal one? I am asking this Q because I don’t know if this is normal practice by all car maintenance workers (this is only my second time) and should I just accept it or is it not how they usually do things and i should change my servicing store.
