In the bit, I imagine she should know his sandwich and its peculiars by then.

It differs in that someone else makes it while he continues the important work of sitting and drinking.

I imagine the small mercy in this Al Bundy kinda situation is that his sandwich is probably pretty simple and boring, mayo and baloney sorta thing, instead of a proper lettuce, tomatoes, cheese, oil, peppers, maybe olives and bologna sorta thing.
