I Can't See Why

I'm sure that you have probably run into this in your travels but never stopped to think about it.

I had to go to my favorite DRIVE-UP ATM the other day. Suddenly, it was staring me square in the face. Why hadn't I noticed this before? There under each button I was to push was the Braille equivalent. WHAT! Braille? At a DRIVE-UP ATM!

Now I'm sure there is a logical reason why this machine would have accomodations for the unsighted, but, you have to admit it's a BIG ? the first time you notice it. I started looking around for telltale signs of an unsighted driver. (broken shrubs, dented cars, prone pedestrians) Nothing! Let me look at the money machine one more time...

Yep! Those little bumps are on the ATM alright, I just can't see why.
