Barber & The King

The barber was giving a haircut to the king and as usually all barbers do, entered into a conversation with his master. He told the King that he is so close to the King yet the king's minister is being paid a very much higher salary. Barber felt that to be rather unfair & wanted an explanation. King said "Ok, I will give you a task which I would normally give the minister, for you to perform so that I could judge" King told the barber "I understand that a ship has arrived in the harbor please brief me about it" Barber ran to the harbor and came back and told the King Yes, Sir. There is a Ship! King: When has it arrived? Barber again ran to the harbor and returned to tell that the ship has arrived 2 days ago. Barber had to run to the harbor several times to the harbor till the king got the required information such as from where the ship has come? What the ship has brought?, Who had come, What they would take back, when? At what Price etc, the Barber was extremely tired after making so many trips. At this stage the King called his minister in the presence of his barber and gave him the same task. Minister made just one trip , came back and gave a report which contained all the info. King had wanted to know.
King then told the barber "This should explain why the minister is paid a higher salary!!
