Have you ever been to a Sheetz gas station?
They seem to have a good UI (although they started working on it over 20 years ago).

Also, what's wrong with a ham and cheese sandwich with mayo and Cesar dressing (in the article)? That's one thing that is great about the Sheetz UI is that I can add buffalo sauce, ranch/mayo, and bacon to nearly every sandwich, which is delicious. My all-time favorite is a bacon, lettuce, mayo, and buffalo sauce cheeseburger or chicken sandwich on a pretzel bun.
