From the article:
When we went to our seats, the wait staff let us know that despite the fact that the previews were playing, we wouldn’t know until the movie actually started whether we could see the film or not. If it didn’t work, the screen would just turn black. Luckily, the film went through without a hitch.
Display it prominently as a warning to any other feet thinking of stepping out on them. Gotta make sure they toe the line. Third foot pun.
