The incident was rubbish. They were not cutting in line, and business class passengers get preferential treatment all over, since they pay more. This was just someone trying to make a 'viral' video , and he succeeded.
This is despite the fact that i think Iftikhar Ch. and his son are both crooked.......and Musharraf himself is crooked times 10, considering that he sold the integrity of the country at the hands of convicted money launderers and criminals in the form of an NRO to BB and Nawaz.
