Why You Should Not Go to McDonald's with a Writer

-Did you want fries with that?
-I didn't before, but I do now.
-So...no?
-No, I do want fries with that. Now.
-Are you going to want fries with that or not?
-Listen, I don't know if I'll want them in the future, but I do want them now.
-What are you talking about, in the future? I just want to know if you wanted them.
-When?
-NOW!
-Oh NOW? I'm sorry, I wouldn't have known. With the tense changes and all.
-Sorry?
-It's okay, you don't have to apologize. Just be more careful next time. Tense is important.
-Whatever. Your total is going to be $6.03.
-When?
-I'm getting my manager.
-Now?
-Yes.
-Excellent. That's all I wanted to hear. Here, keep the change.
