Do as the Chinese do and just walk right through: you're not the asshole.

Undisciplined

agreed, def try to stay very aware of this when Im traveling too.

It's the same energy as people at the gym expecting others to wait/move aside while they record their random video

What's a weird social "norm" that shouldn't be so normal?

Here's one I completely changed my mind about while visiting China: expecting everyone in a public area to stand aside and wait for you to take a family picture. 

Clearly, the family holding everyone up is the selfish party, not the many other people trying to go about their business. If you want to stage a family photo in a crowded place, you can wait for a break in the crowd or take an authentic picture with randos walking through the frame.
