We were there a year ago, wifey wouldn’t let us do that, it was a struggle just to get her to stand on the glass floor looking down at the street from the top of the tower.
We were there a number of years ago and my wife would not stand on the glass squares no matter how much I reassured her it was safe. While people watching there we could see that the tourists seemed to divide into three groups - those would not go near the glass floor, those who would carefully walk along the opaque sections between the squares and those who ran right over and stood or jumped on the glass.
