So their father was confused and decided to pay a visit to the boss, who told him that he would let his sons explain for themselves.

The three brothers were asked by the supervisor to go to the airport to get a cargo inventory at different times. Jim, who received 500 dollars a month, got the information on the phone instead of going to the airport himself. Frank, the 1000 dollars a month brother with a list of more cargoes. George, the 1500 dollars a month brother came back with detailed information and also did something extra without being told.
