Gah. Just looking at them makes me all blinky. This obsession didn't start until I worked in retail at the age of 16. I worked at Fashion Bug for years. At some point I started worrying that I would turn around too fast and gouge my eye out with the end of one of the racks and lose my eye. This made it unbearable to go to work. I wanted to wear safety goggles to work, but I knew that was weird so I just made sure I walked slowly around the store when putting things away and tried to work the cash register as much as possible.
Even today I'm scared of them. When I go shopping I'm always on high alert for eye stabbage. I'm always afraid I'll be unaware of my distance from a rack and smash my face into one. Which is ridiculous since I'm hyper aware of the racks and my distance to them. But I'm also clumsy. So what if I trip on the carpet, my own feet, the air and land eye first onto a rack arm? So risky. I just try to stay away from those kinds of racks in general. And mostly online shop. Eeek.
