I discovered this year that there was an unspoken rule to get on the bus in the order you arrived at the bus stop at. I had never paid attention to this and just got on in order of proximity to the door when it stopped until I got yelled at. I thought the guy was just being weird but I’ve paid attention since and it is absolutely true, people will move away from the door to let people who have waited longer board first.
Not sure how universal this is, I’m in the UK.
