There are no credible sources that assert this was a real event, and had actual witnesses. You seem to be mistaking the story as objective news.People argue all the time. However the event was witnessed and documented. People may opt to not believe, but we do have records of the events.
This isn't a story about a guy eating a ham sandwich, which is believable. It's a series of stories with supernatural elements, and that makes them implausible and requires exceptional evidence to show they are true. There is none.
