Relation still returning row even if data not exist in laravel

I have this query :

 $data=Booking::whereHas('service.user', function($query) use ($id){
                    $query->where('user_id', $id);
 })->get();

Here service.user relate to user, i want to return only those record from booking table where user_id exist in service.user relation but using this relation i'm still getting record from booking table when the user_id is not present in service.user relation. Can anybody suggest some solution. Thanks
