The men flop from the chair in surprise. Fortunately, they remain unharmed and laugh after recovering from the horror. The elephant is a little startled and doesn't quite understand what's going on. As can be seen in the description of the video, elephants cannot look so well. The pachyderm had smelled the food and wanted to get something. It was therefore not an intention, rather an accident, that he would pull the tourists off their chairs. The men just sat unfavorably: between the elephant and the feed.
