Blimey, Kid, where is he? They wouldn't let anyone back in to our building once we were out - we had a ludicrous sitution where staff were signalling to each other out of windows to collect things like house keys off the desks of people who had gone to lunch and couldn't get back in - but they were happy for us to go out if we headed away from the tube. Actually, to begin with they said i couldn't take my car out because no movement of traffic was allowed - but then decided they wanted the place for emergency vehicles!
Hope it's 2 hours, not 36, Kid
