Regarding the Wine Train article and the ladies who were removed from the train, the article gave the impression that any apology would be unacceptable, although I am not sure that is the case.
I think a very simple question can be asked of them: "How can we make it up to you?"
There seems to be a single spokesperson for the group, and I am assuming she is speaking on behalf of all and represents all of their sentiments.
You have free articles remaining.
Even still, it might be worth asking each individual that question so that each person can decided what would be most fitting for their personhood.
