Waiter: Would you like some coffee?
Woman: Yes, please.
Waiter: Just say when. (starts to pour.)
Woman: There. (He keeps pouring.) That's fine. (He pours.) Stop! (She grabs the pot; there is coffee everywhere.) What are you doing? I said stop.
Waiter: Yes, ma'am.
Woman: Well, why didn't you stop pouring?
Waiter: Oh, I wasn't sure you meant it.
Woman: Look, of course I meant it! I have coffee all over my lap! You nearly burned me!
Waiter: Forgive me, ma'am, but you certainly looked thirsty. I thought you wanted more.
Waiter: And you must admit, you did let me start to pour.
Woman: Well, of course I did. I wanted some coffee.
Waiter: See, there you go. A perfectly honest mistake.
