It's a habit in specific countries, China is one in my experience.
1) long voice memos over succinctly typed notes
2) not forming lines/queues and just mobbing the train/shop/etc
3) habitually late or not on time
Also even queueing can have different norms. Here people rush to a newly opened supermarket checkout like their life depended on it. I feel that should be a lot less sociably acceptable than it is, especially for those with overfilled carts that will add huge delays for anyone behind them.
