A really interesting story, and a valuable lesson for all ranks.
The MBWA that a_a talks of is a good idea, but only as long as it's done with sincerity - I'm sure his dad is popular to this day as a result of him wanting to do it on his own accord, not because someone has said it's a way to manage, we're dealing with other humans after all, and as we're taught from an early age - treat others how you'd like to be treated.
