Same here - in the meantime I'm reminiscing over the ordering habits of Robert Dupea (Jack Nicholson) in Five Easy Pieces:

Dupea: I'd like a plain omelette, no potatoes, tomatoes instead, a cup of coffee, and wheat toast.
Waitress: (She points to the menu) No substitutions.
Dupea: What do you mean? You don't have any tomatoes?
Waitress: Only what's on the menu. You can have a number two - a plain omelette. It comes with cottage fries and rolls.[/QUOTE]

A great scene that clearly demonstrates the idea of "thinking outside the box". Nicholson ends up ordering a chicken salad sandwich to get his toast, but tells the waitress to hold the lettuce, tomato and chicken salad", but that she should charge him for the sandwich so she's not violating the "no substitutions" rule. Classic.
