Palms Up

Place Both Hands Palms Up, And Toward Back

Does this meant it won't dispense towels if your Hands are Palms Down? My sister-in-law used her foot and it worked just fine so I don't understand. 

Plus, the magic eye - the gizmo you're trying to trigger with your upward facing palms - isn't in the back. You can't see it in this picture but it's actually front and center so regardless of which way your hands are facing, it won't dispense anything if you're on either side of said gizmo and Toward the Back.

And What's With The Capital Letters? Did They Run Out Of Little Ones?

My suggestion is make sure you know how to operate all the bathroom equipment before using it. Otherwise, you may find yourself with a handful of soap and no way to rinse them. Or, dripping hands with no way to dry them. I would say that the stall doors have changed relatively little over the years and are still easy and simple to operate but I know that's not strictly true.

And toilets? Don't Get Me Started
