Simple geometry would suggest that the middle position should not be there. In fact, the more mathematically oriented will point out that the middle point of a square with six feet sides is only 1/sqrt(2) of six feet or about 70% of the required distance…

I am not sure why they put this there. This is in the elevator to the United Club in Newark airport. I was going to ask the lady at the counter but between my mask, her mask, two layers of plexiglass and six feet of separation, I thought the better of it!!

The math nerd in me still protests!
