Where do you live that your McDonald's has a steak sandwich?

They certainly don't have anything like that in most of the US.

Sometimes there's a breakfast "steak" egg and cheese bagel, but that's clearly not what you're talking about, and it's as much of a "steak" as a McRib is ribs...

(Also what does a steak sliced in two even mean? Steaks can be cut whatever thickness you want, every steak is just a slice of a larger steak. And the total amount of meat is determined by pre-portioned weight anyways.)
