Obviously this clashes quite hard with cyberpunk using the aesthetic of Asia for characters who epitomise American ideas of rebellion, competition and countercultural coolness...
Also, "filial duty" is pretty strong across a number of Asian cultures. i.e. you should be thinking of your family (parents, grandparents) before yourself.
Does this go the other way too? Is the boss staying late (with the expectation that others do so as well) considered rude because it inconveniences his workers?
Because if not, this has nothing to do with being polite and everything to do with power and deference to power.
That doesn't dismiss the concerns about deference to power though.
Google "chinese spitting" [1] and then extrapolate form there.
