Adverse Effects of Hunger

Waiting in line at a Subway in Beaverton, the guy in front of me couldn't quite comprehend the questions he was being asked by the girl behind the counter.

Girl: "Welcome to Subway. What kind of bread would you like?"
Man: "I want a ham with american, tomatoes, olive oil, salt and pepper."
Girl: "...what kind of bread is that?"
Man: "White."
Girl: "That was a ham with cheddar, right?"
Man: "No, american."
Girl: "Would you like that toasted?"
Man: "Not toasted. But I want tomatoes, olive oil, salt and pepper on it."
Girl: *finishes putting on cheese* "Someone else will take care of the rest of that for you."
Young man behind the counter: "Any mayonnaise or mustard, today?"
Man: "Just tomatoes, olive oil, salt and pepper."
Young man: *Finishes sandwich and passes it to the cashier*
Cashier: "What kind of sandwich did you have today?"
Man: "12 inch ham with american, tomatoes, olive oil, salt and pepper."

Now, I understand not understanding the process of the average sandwich shop. But he obviously knew the stuff that goes on their sandwiches. I go into this one quite often and those people behind the counter know how to process through a lunch crowd of picky business people. I guess the guy just really knew what he wanted?
