Dog Robber? I heard this term for the first time today. Then I did some research. Here is what I found out.
During American Civil War, enlisted men in the army were called “Dogs”. The commander of the army unit had a personal assistant. His job is to get the best available things for the commander = Food, Clothes, Liquor, Girls. He would most of the times steel from the enlisted men (Dogs) and bring to the commander. In other words, the personal assistant will obtain whatever his superior wants by any means necessary, legal or otherwise. Therefore, this personal assistant was called Dog Robber.
During World War 2, this name was changed to Aides in the US Army.
In India, they are called Orderly or Aide-de-camp. Even police officers have orderlies in India. Though they are not supposed to do any personal household work, it is what they do all the time.
Here is an interesting story. There was an Army General in India. His daughter went to a name brand university in a city in India to do a special course for 6 months. The General transferred a Major (who knew the local language and familiar with that city) to that city for 6 months on special assignment. His assignment? Take care of the needs of his daughter.
