You're being downvoted because you clearly didn't read the article, despite your claim that you did. It's a funny post about how people order and share, not about bill-splitting.
I find it amazing how some people can make uninformed claims about something, and when their "knowledge" is called into question, instead of backing down, they choose to double-down and insist that they are in fact informed. All the while, plainly verifiable evidence is staring everyone in the face that they don't know what they're talking about.
Adversarial? I don't believe you read the article. The article talked at length about why having an adversarial approach to dinner was a poor choice, and concluded with the idea that couples should practice 'full communism' at dinner, i.e., full cooperation when choosing the food and sharing it freely when it arrives.
