Basically explain what you get on your sandwich, whether it's toasted or not, what bread, etc. If you don't order the sandwiches, just say what you get anyways!
I almost always get the 6inch Italian Herbs and Cheese bread. With ham and American Cheese and toasted. I also have mayo poured on it, like legit POURED. Basically enough mayo to make the sandwich grow taller a whole inch.
So yeah
