Regional Differences?

I visited 2 5Gs in Idaho over the weekend, and I believe I have encountered my very first case of regional differences between the various franchises:

Fry Sauce!

It was in one of the pump canisters, where normally there are two ketchup. I bow to the Idaho potato expertise; if they think fry sauce in necessary on fries then so do I.

Now, I have only been to 53 stores, in 9 states, so the other 450-odd stores my have other regional differences. anybody aware of any others?
