There's some good advice here, such as, giving up your seat for pregnant women.
But apparently these self-styled subway experts committed some etiquette mistakes of their own (you're not supposed to "hug" the poles with your arm like that).
Also, there were several topics I would have liked to have seen covered:
- How do I handle a stroller on the subway?
- How do I avoid getting those annoying "please swipe again" messages?
- How much Axe Body Spray is too much?
Maybe they can do a sequel.
