The facts are that you have flown, landed, the doors are open and now, as a passenger, you are waiting for something to happen. The flight is legally over so now the Capatin is just a mere human being. No memo any Gob****e in O'Leary's caravan does anything to enhance the former captain's status. If you want to get off, you get off. Finish! Nobody has any rights to detain you against your will (in Europe). Your job as Captain is now to try to get what's left back to wherever your company want it, when they want it. So if Pax want to get off, let them. Just remember who has got off and if they had any checked in bags. When the next flight starts, you are Captain again and have all sorts of wierd and wonderful powers!
