How to unset session container of checkout at order process

[GuillaumeM69]

Hi, Somebody has an idea to unset only the container of checkout "speck_checkout_strategy" on the last step and not all the session container like zfcuser ?

[GuillaumeM69]

public function destroyService()
{
$container = new Container('speck_checkout_strategy');
unset($container->strategy);
}

If you have a best idea !
