Cornishscot, perhaps your difficult journey didn't help your goal as a casting volunteer. I'm guessing it would make you a little flustered (unsurprisingly) and given the amount of work and potential issues they are facing, I suspect one of their major requirements was staying calm under pressure and not flapping. While you could give examples of it in the past, most interviewers are going to be swayed partially by the evidence in front of them.
