Unless one knows the exact circumstances, it is inappropriate to be calling for apologies from anyone. If, for instance, the crew had made an error of judgement, but were allowed off with a warning, would it be appropriate for Qantas to offer an apology?
The crew concerned may be innocent or guilty and still have their jobs. Lets not be pointing the finger at Qantas or the crew without knowing all of the facts. Perhaps it is better that we just remind ourselves to be careful and not act inappropriately.
