Well done Rag.
I must agree with you. I hope this was the point I was trying to put across earlier. As I said the biggest mistake we could make is to drive people away, and this sometimes means making the 'offender' aware in as nice a way as possible that they need to get in time or quieten down. I've done it by saying 'It's your turn now' - the astonished look on faces can sometimes be a joy in itself.
