You're walking along the street. You need to go to the washroom desss...perately. What do you do? If you can't control yourself, you could be embarrassed to no end.
Don't worry. Someone in San Francisco has invented a self-cleaning public toilet. The toilet cleans itself. The seat goes back into the wall where it is washed and blow-dried. Even the floors are washed automatically. You must be quick,though. You've only got 20 minutes to "do your business." Then, there's a 2-minute warning before the door opens. When it does, you'd better be ready or your face will be red!
