Years ago, I went to vote in a local election. For some reason, the election took place at a different polling place than usual. While I imagine most voters took this in stride, at least one voter was irked.
"Why is the polling place different this time?" a voter asked one of the polling place workers. "Why, if I hadn't read the card you mailed about the change, I never would have known about it!"
"That's what the card is for," the worker replied evenly.
I'm still not sure what sort of notification the voter expected.
