I have always wondered why there is brail on a drive through ATM
I agree that it seems silly, but it's simply so that visually-impaired people can use them. No, of course they don't drive themselves up to one. But they can be driven
to one. And the braille allows them to use the ATM just like anyone else.
I've seen it many times.
A) I once worked in a bank where we could view the outside ATM machine.
B) my town is home to the Illinois School for the Visually Impared, so there is a community of VI people that live here.
so, A+B=C; where C= seeing a VI person using the braille on an ATM machine.
