Okay...explain this to me

Here is a picture of a snack vending machine. We have a few at work. Notice the front is glass, you can clearly see what's in it. Right? On the little numbered buttons are the raised braille bumps. Braille...Okay I get that the vendors have to be pc or non-disciminatory or whatever..but, honestly, what good is the braille if the poor bastard can't see what he's selecting??
