You're absolutely right. I was sitting in church one day, towards the end of a rather lively service, and a bloke ran in shouting "Will you all get out now please?" We all just looked at him, wondering if this was another innovative bit of the service, and he continued "You need to get out of the building. There's a fire". He seemed very perplexed that we were not jumping up and following his instructions immediately. We wandered outside and there was indeed a fire - a digger had hit a gas main and it had gone up in ten-foot flames right outside the church. Later on as we were all hanging around amongst the other evacuated locals, the bloke explained that he was a policeman but had forgotten when he ran into the church that he wasn't wearing his uniform!
