A pet peeve?

So, I'm in restroom of a restaurant yesterday and as I've seen many times before the sink is on one side of the restroom and the handdryer/paper towels are on the other side. When I see this I have to ask myself why does anyone who designs these places do this? Why do they want people with dripping hands to track water across the floor of the restroom? Wouldn't this cause a potential danger with a wet/slick floor? It just doesn't make sense to me. Is it a trivial thought? Perhaps. Must be a pet peeve. This just bugs me.
