What happens if they vote "No" three times in a row (no deal, no no-deal, no postponement)?

If this wasn't politics I'd say: See if you can simplify this function, bonus points if you can avoid error conditions too:

    func brexit(){
       if(deal){
            exit(deal);
        } else {
            if(!deal) {
                exit(null);
            } else {
                if(postpone){
                    wait(TIME);
                    brexit();
                } else { 
                   throw new handsInTheAir();
                }
            }
        }
    }
