Have you ever been to a drive up ATM that had braille? I have. Bunch of people going to be looking next time they go to one, too.
In college we had a bank manager come in to talk to us in whatever class, and at the end where we were allowed (supposed) to ask questions, I asked why do drive up ATM's have braille on the keys. She was dumbfounded, kind of looked like she did not believe me. But she was the manager of my bank and I knew it were true at the bank she managed. Within a month the drive up ATM's were changed out. I thought that was kind of funny.
Because the same ATMs are used on sidewalks in cities.
