I was at the new Circuit City in Brookfield today getting a satellite radio installed in a friend's vehicle. At the back door, which was locked, was a sign that said "Push button for service". Beneath it was written, presumably, the same thing in braille. The only catch was beneath the braille were several arrows pointing to the button on an adjacent wall and beneath the arrows was an alarm system keypad. So basically on the odd chance that a blind person should actually find and read the braille sign, they'll start pushing the alarm system keypad because there was no braille message indicating for them to follow the arrows which of course could not be seen by them anyway. It could be an awkward situation if it actually happened but what are those chances? I've never seen a blind person feeling around randomly on walls looking for braille signs. Have you?
