That's a problem for the parents to solve themselves without forcing their judgment onto someone else who has nothing to do with their assumptions. If that means they have to change their own morning routine, then so be it. That's their decision to make. What wasn't their decision is to dictate the actions of the bus driver.
I'm directly criticizing the parents for how they handled this. They are in the wrong for what they did.
This man did nothing wrong on his actions and yet was punished due to the shortsighted assumptions of judgmental people.
