I have no idea where this happened but this right here is why I’m afraid of escalators. I had a family member who got their shoelace caught in one and they would’ve severely damaged if not lost part of their foot had they not gotten the shoe off in time because that shoe was ripped to shreds. This could be in China since nothing seems to work there but surveillance cameras capture the moment an escalator breaks and everyone goes tumbling down with it. The worst part is the poor guy who falls in the gap and then is covered by the stairs again. God only knows what injuries he sustained but I think this is incentive to use the stairs from now on.
