I just noticed that there's a vending machine where there are Braille dots on the number pad where you choose your selection - at least the atm's that I've looked at have other information for people who read Braille - but a vending machine? Odd...

As for why they have braille on drive up teller machines, well...you can't expect the dog to drive *and* use the teller machine.
