On the escalator.

A man in a white t-shirt rides an escalator upward, approaching another man in a black t-shirt who is standing on the escalator. The man in the white shirt extends his arms and yells at the man in the black shirt, who turns to face him. The man in the white shirt then turns and rides the escalator down, while the man in the black shirt remains standing. The scene takes place in a crowded indoor area with an escalator.
