Is he hitching a ride, or is he simply the ayudante. These buses in Guatemala typically have an ayudante (helper), whose job it is to assist passengers and their baggage. It is common for the buses to be driving down the road while the ayudante arranges luggage on the roof. The driver sometimes slows down enough for the ayudante to move between the front door and the back ladder. If the ayudante wishes a stop, he likely has to wait for the next passenger pick up.
