Gimme a break, these are HOT DOGS not frankfurters.   They've been called HOT DOGS for a century or so.   Just as we wouldn't change French Fries to Freedom Fries cause Georgie B says so we also aren't going to change HOT DOGS to some out-of-date hickville term like frankfurters cause some bloke down underwhere says thats what his mommy calls them.   Times change, buddy.   And Australia has a grand total of 20 million people, half of them speaking English as a third language.
