I think I have mentioned before when working in telephone enquiries about my dealings with the military on Sunday afternoons. The call would often be made my mum who would then be passing the information backwards and forwards. We would usually have to identify the station for the camp. As this was often after tea then the chances of covering the distance from home to camp at the opposite end of the country that night was nil. When informed of this the mum's response was "But he'll be on a charge."
