Everyone does busses differently. Some, like Singaporeans, stand patiently aside as the train empties and file in quietly. The Japanese are the same and don’t whisper a word as they are tucked into metro carriages.
In Quito, they lineup for the bus in a single file. Then, just as the bus doors open, they pile in with reckless abandon. The same was true in Medellin mind you. But there was no sense of order in Medellin; you knew what was coming.
In Quito, they politely line up. Then rush the door.
