Why is there brail on drive up atm's? I mean its not that this really bothers me unless theyare expecting blind people to drive. But this question has racked my brain for somtime and i want an answer to it lol. Maybe its just cheaper to not use differant buttons on them and have the same for every one or maybe they don't know where the atm is going to be set up i don't know. Any help on this one or if you have a logical answer or just somthing to say let me know.
