At work there is a convenience store in the building next door. It's manned by a guy who is completely blind.
I went with Paul yesterday and today for snacks. He knows (or at least I think he does) every price on every item in the store, but you have to tell him what you are buying. You also have to tell him how much money you give him which seems like a gaping hole for scammers, which he puts into a talking cash register.
I want to ask him how he ended up this job but that's probably not PC. Its so strange if its a program match up the visually impaired as cashiers.

He is so sweet. :-)
Wow, that's awesome. I've never heard of that.
I guess if he runs the entire operation it makes sense that he would know all the prices too.
There is a state program for the visually impaired to run newsstands in state buildings :::link:::
