In England in particular into the 1970s and elsewhere, public transit buses kept the driver separate from the passengers, a conductor dealt with the passengers. You paid the conductor the fare necessary to reach your destination (fares were by distance) and then were given a ticket. The conductor then watched to make sure you didn't try to stay on the bus longer. This made loading and unloading buses very fast, as no fare payment was necessary until seated. Many have seen double decker buses with an open-air platform at the back with a pole. you could actually run up and jump on the bus while it was moving, if you dared. there were no doors.
