I don't think it is having the stub checked at the aircraft that is the problems, its the queuing up to get a passport check and boarding card stamped, then again to to pass the barrier and receive the stub, and then again to queue on get on the aircraft, all while trying to juggle bags and pieces of paper. That coupled with the nonallocated seating bundle to get on some LC carriers can try the patience of a weekly commuter saint. That in no way excuses rudeness. There must be an easier way...
