Ha, I been meaning to post this for a long time now. When I went on my trip to Chicago and Ohio, I was amazed by the toilets at the Chicago O’Hare airport. They have this system that after a flush, you wave your hand in front of this sensor and it put a new toilet seat protector on. Fascinating. It also counts down how many protector are left in the system. I wonder if it pages the janitorial staff when almost out? Most of them had about 40 or so left…wonder if they start at 100? Deep questions deserving some deep understanding. Anyways, here is the video I took below (I know, werid…but like I said, I was totally engaged in this whole process).
