Picking a seat in the bus, the Norwegian way
(Might apply for other Scandinavian countries and certain other countries as well, see video of Swedish people waiting at the bus stop at the bottom of this post. )
As you walk into the bus, scan the seat rows.
Some seats are prioritized for elderly and disabled. Stay away unless the bus is empty anyway.
Try to find two empty seats next to each other, take one, put your bag in the other.
Generally within reasonable limits try to contribute to an even distribution of peiple in the bus.
If you see a friend (who's not extremely close friends,) or someone you know, smile and say hi or nod.
If you cannot find two empty seats, pick one based on the following list:
Someone you know
Take with a grain of salt, and always apply common sense. Also it is a bit short; I wrote it in around 15 minutes, on the bus.
BTW, avoiding people on the bus is seen as polite, even if you know them.
Will try to get back with some advice on how to pick a seat on the train (if you can get one, that is 😎 )
