It's quite handy, actually. I usually vote at the same place where I get my groceries - I go there a couple of times a week and just pick a time when there are no queues to the voting booths.

The pre-election voting places usually look something like this. You just show your ID, they give you a ballot, you go to the booth to fill it, have it stamped by the official, put it in an envelope, sign a paper to confirm your identity, and you're done.
