Dear Mr Putin ... These are only hypothetical "banking manoeuvres" and staff training. At the same time we will be testing our control systems and polishing the on off switches to the control boxes. We may even make more rigourous checks on the safety protocols if we feel it prudent. Feel free to make constructive comments but do not try to interfere with our rightful concerns for all our clients safety and integrity. We also reserve the right to pass on to you any costs that are incurred by your actions and will automatically debit your accounts to cover our expenses and time.
