A silver watch is on his left wrist. 3. A male in a dark grey patterned long-sleeved shirt, dark grey jeans, dark-framed glasses, and black leather boots is seated with his right leg crossed over his left, looking down at and operating a light-colored smartphone with his left hand. A silver watch with a dark face is on his left wrist. To the far right, partially visible, a fourth male in a yellow collared shirt and dark pants is standing, gripping a vertical yellow and silver grab pole with his right hand. A blue cloth is visible tucked into his pants or belt. Resting on a yellow textured mat on the brown floor near his feet is a dark blue cleaning mop with a white and blue handle. A green GrabBike advertisement poster, featuring the text "MURAH NON-STOP" and "Cek Sekarang!" in Indonesian, is prominently displayed on the light grey train wall above the seated passengers. Overhead luggage racks are visible, and windows show a dark exterior.
