Does no one else note the irony of this poster's user name for not appreciating and respecting the cultural differences of another country influencing the expectation of someone in that job to take these actions?
Well, I don't appreciate all the cultural traditions in my own country or culture, also. Will not go into detail at the moment. I did marvel at the order and harmony in Japan, but sometimes questioned whether the cost was worth it (as did some Japanese people I knew). I also appreciated how safe and supportive the country once. For example, once I was at the train station and realized I had forgotten my wallet. The police box, or train station box at the station, gave me the fare and I filled out an IOU.
And Japan didn't do to shabbily by me, given that I wrote more than a few articles about Japanese businesses and individuals/artists for English speaking magazines. I even had a cover story in the magazine for Japanese Airlines, which was well-regarded (about the changing role of Japanese men in society), and also a cover for another Japanese airline magazine.
And I did not disrespect this person or say anything, I just found the situation absurd.
BTW, my username refers to skaters - Takeshi Honda and Fumi Suguri. I've always had a fondness for some Japanese skaters, Machidi being my most recent. And of course I love Dai just like everyone else.
The idea is to acknowledge anyone who is waiting to get on. It's not for your benefit as you are already on.
I totally get that. But no one was getting on - or getting off.
To give an analogy, imagine a store greet at Walmart or any other business that has a greeter. The greeter is nodding and saying 'welcome to Walmart, thank you for shopping', but there is no one on the receiving end of the greeting.
Do you think that no-one would find that odd?
