I read the chain, and it's 2 comments long, and that one person randomly brought up healthcare systems as a total non-sequitor.
The original comment is about her damaging the machine. It stands to reason this person thought she was on the hook for the damages, which is never discussed in the article, nor is damage confirmed.
I agree that part was a non-sequitur. I even thought so myself when I first passed over it.
But the other part of the exchange is not confusing at all and there's zero indication that anyone thought she is actually on the hook for any damages. I'm more-so confused how you could not pick up the meaning even after a re-read.
