Rule of the Games - Telegraph Border Force staff have been instructed to give a warm personal greeting to travellers arriving in this country during the Olympics. If they have spent several hours queuing in the immigration hall, new arrivals may find a cheery "welcome to London" hard to take. Perhaps the immigration officers could offer a more practical word of welcome to our Olympic guests. "The M4 is closed but the South Circular is quite scenic" would prepare them for what may prove a stately progress to their final destinations. "Did you remember to pack your wellies?" would alert them to the delights of our matchless summer weather while "we drive on the left unless you are a member of the Olympic family when you will have your very own lane" would keep them safe. And finally, "don't worry about the soldiers everywhere - there really hasn't been a coup."
