lemme explain
interesting cartoon but its not right. the reason that there is braille on the drive thru atm machines is NOT because its easy for blind people to use, as your cartoon cleary illustrates its unsafe for blind people to use drive thru atm machines.
THE REASON THAT THERE IS BRAILLE ON THESE ATM MACHINES!! is because its cost effective. they only need to produce ONE(1) keyboard for all atm machines. think about it, they need braille on the keyboard on the streets, this way they only need to manufacture ONE(1) kind of keyboard. GET IT, GOT IT, GOOD!
