The bogs at City and elsewhere have improved immeasurably over the years. BITD, you got a full on Bobby Sands experience at some places, with Izal if you were lucky. Now it's no graffiti and V I Poo. If I am caught short on a train, I always try to evacuate in Leeds station before the train pulls out. Similarly when journeying by air over Europe, I try to 'go' in French airspace, ideally over Paris.
Was it that the Alarms were going to show a prospective buyer around, but they didn't want the fans inside, however talks fell through, so the evacuation was cancelled.
