This shoeshiner robot machine was at the entrance of the city's main subway station. I would be a little afraid to stick my feet into that machine in case it doesn't let go.
I saw this little neat gadget at Kentucky Fried Chicken fastfood restaurant. It dispenses a little wet napkin with a push of the button. I think the little light in the middle indicates how many napkins are left in the machine.
This isn't a very good picture, but it's a cup sterilizer machine on the right and a water dispenser to the left. When people buy a meal at the food court they can get a free drink of water by grabbing a clean metal cup from inside the sterilizer machine and filling it up with hot or cold water. Used cups are thrown into the opening at the bottom of the sterilizer machine. A woman comes by and picks up the used cups for cleaning and then returns them to the sterilizer machine.
Do you like sharing soap in a public bathroom? I had to take a picture of this to show you it does exist.
