Well, I don't know why they have braille on the ATMs. My only guess is that blind people have not-blind friends. They probably don't want to give their PINs to their friends.
Also, most people can't learn braille. Have you ever put your fingers on those little dots? Usually, people with sight don't have a sense of touch developed enough to feel each letter. Now, you can force yourself to count each little dot on each little row, but you'll probably never be able to go fast enough to actually be able to read a whole sentence in less than half an hour. Also, there are blind people that can't read braille and a very few people with sight who do possess a highly developed sense of touch.
Maybe ecstacy would help you with learning to read braille... if you could stop gnawing your lip long enough.
Oh, I hate you all so shut up and die!
