Hahaha, I like how words change like that based on region. I've found quite a few things like that since moving. It can make me sad sometimes because I get homesick, but mostly I think its interesting to see different words used to mean the same thing, even within the same language. Like sometimes here, people call license plates "tags". I had never heard that one.

Anyways, I don't think it matters too much. It tastes the same no matter what you call it I don't think there's a right or a wrong way to say it. I was mostly just curious to see if it was just my little area that called them chicken burgers or maybe sharkys little area that called them chicken sandwiches. Seems like its mostly an American thing to call them sandwiches. So now I know!
