your quote does make sense..but let me put it this way when there is a huge line at the security and passengers are in a hurry to get to thier flight...us screener or employees are here to help you get through the line quickly..not waiting in line and not taking off our shoes (which we would have to because most of us were profiled shoes) or getting them swipe would take longer therefore to open up a line to get the passenger screened would take longer, passengers would get upset ect ect ect!! thats one of the reasons why we are exempt same for pilots and flight attendants if they are not ready for thier flight your flight is not leaving on time!!
