I sell rolled ice cream and fro-yo in my capsule located on the second floor of the viaduct. I prepare my products on the first level of my capsule and serve them through the shutter opening. At the same time, my sink is located on the first floor. Then I climb the climbing stairs and go to the second floor. The handles of the ladder extend to the rack arrangement on the side, so you can easily pull yourself out of this extension after you climb up. By the way, you can go to bed when you keep climbing on the climbing ladder.
