The bus just happened to pass by the falafel-selling-vender truck with the door on the street side open. The bus paused in traffic giving me the chance to see what the lone server inside was doing, as I noticed he was in motion toward the open door. He was arranging the flattened cardboard box on the floor at an angle. The space was small, and he was tall, but he proceeded to bend down, and to fold himself into a kneel, I presume to pray.
