namespace Thunder\Bundle\SthBundle;

use Symfony\Bundle\FrameworkBundle\Controller\Controller as ControllerBase;

class Controller extends ControllerBase
    {
    public function usefulToolThatDoesNotFitIntoService()
        {
        return $computedUsefulValue;
        }
        
    public function anotherBundleWideToolSharedAmongControllers()

        }

        return 4; // based on a fair dice roll
        }
    }

SthController.php

<?php
namespace Thunder\Bundle\SthBundle;

// using local namespace resolving, one `use` statement less
class SthController extends Controller
    {
    public function indexAction()
        {
        $view = array();
        $view['foo'] = $this->usefulToolThatDoesNotFitIntoService();
        $view['bar'] = $this->anotherBundleWideToolSharedAmongControllers();
        return $this->render('template', $view)
        }
    }
