Braille on ATM's

I know that there is an ongoing joke about braille being on Drive up ATM's. People do not seem to realize that just because they are blind does not mean they do not have the right to privacy just like everyone else. You may ask "when would a blind person need to use the drive through ATM?" Well, I have a scenario. Say it is late and a blind person needs to withdraw some money from the ATM. So a person drives the blind person to the ATM and because of the braille on the machine he does not have to tell anyone his password or any information for that matter. So, in conclusion- people should continue to tell these jokes, but be aware that there is a reason for it.
