Family bathroom
This one is a little bit weird for us but at the end of the day, it makes a lot of sense. You are an adult in a public place with your kid and you need to go to the bathroom. As you enter you may feel a little nervous about going into a stall and leaving your child completely unattended.
Well, they actually have these special types of bathroom stalls that are large enough for two people, specifically a parent and their child. This is so the adult can watch their kid as they take care of their business and not have to worry about them wandering off or getting taken.
