I expect that it's an example of function over function. As for stalls, traffic flow (also consider where the door ends up hanging as the hinges loosen), fire codes, privacy, cost, and tradition/habit probably all have a say. As for entrance doors, many public facilities use labyrinth entrances these days.
This is a common frustration, but I don't think it's about architectural arrogance.
