Except that in the land of McDonalds they have competition. Subway opens across the road, KFC around the corner, or in reality build another store! So all those cars in the queue decide that even though KFC or Subway cost more theyll go there and save half an hour of their time. Perth airport have no competition so can get away with outstandingly poor service. Announce a brand new airport on the northern outskirts of Perth with a train link and watch how quick YPPH builds a new runway and terminal.
