Every day, all day, I watch the same scenarios before my very eyes. My mind is numb. My eyes are sore.

There's 2 options for people. 6 stairs, or a ramp right next to one another.
I watch the public: guys with canes and 2 bags, old, hobbling, barely able to walk folks, people with carts, people who don't even come in the building with a lot of stuff in their hands, people who take the stairs then realize something and go back down, or barely mobile folks, TAKE THE STAIRS, for 5 minutes, sometimes 10.
You cannot teach common sense, and the most common, everyday, basic person lacks any common sense.
