I can't see how they are in the wrong here.

Your SO showed up with another child who, by all accounts, had fun "helping" and then after the fact, he decides he should get paid and confronts adults to ask for money. That was a good time for you to step in and explain how inappropriate that is.

If anyone should be paying him, I would think it would be your SO who "subcontracted" some of his work.

In other words, I would have heard, "quit your crying or I'll give you something about".

I also would not be able to leave one person out, but that's me.
When I hear terms like "hipster" I think, who told cliques they could leave high school??
