> I was young enough in my career to just accept that
This reminded me of two much smaller-scale events from my personal life:
1. I engaged a Chinese tutor. After several weeks of lessons, one day I found that I had forgotten to bring my wallet to the lesson and couldn't pay her. I considered this a huge faux pas, but she treated it as a non-event, brushing it off with "no problem, just pay me next time". (Which I did. The inability to pay that week was just an accident on my part.)
2. Living in China, I arranged for someone I knew through a board game club to help me order an air purifier online. She would buy and receive the air purifier and then hand it over to me.
She notified me that she had received the air purifier and I went out to pick it up from her. We had a short conversation and I took it away. As I was riding home, I got a message from her: "It seems we both forgot the money."
So I offered that I could either come back right away to hand over the money, or give it to her the next time I saw her (presumably at a meeting of the club). She wanted me to come back right away.
I did, because obviously I have the obligation to pay for my thing. But in that case I was slightly hurt by the implied lack of trust.

The incident with the tutor occurred in a context where I had already built up some payment-related trust, so I can understand why things happened that way.
