Apparently, the buttons can be programmed into any configuration or locked out, based upon client need.
I have personally used elevators in Asia where the close door button will immediately trigger closed. If a person runs for the elevator, you can “bounce” the doors open.
Korean elevator etiquette is almost identical to Japan, but somewhat more impromptu. I remember a commercial (maybe PSA) where a woman ran to an elevator at the last minute and stuck their foot into the door to trigger it open, inadvertently kicking a man in the crotch.
But this experience was inconsistent, and depended upon the building. Due to urban density, you spend a lot of time going up and down elevators there.
Elevator etiquette could be amusing, … “hurry up and wait,” … particularly if the elevator (or subway train door) was slower to respond than everyone on it expected.
