In-and-Out burger has an odd way of taking your order. You say, I want a hamburger.
They say: With everything?
You: Yes, with everything.
They: Would you like onions?
You: Yes, I said everything.
They: Everything and onions?
You: Yes, everything and onions.
They don't take the word "everything" seriously. Everything includes onions, I would think. But they always ask about onion after you've told them you want everything.
I imagine because there are enough people who when they say "everything" forget that onions might be involved.
And so you hand them the hamburger with EVERYTHING and they say, "Oh, I didn't want onion."
Too bad, so sad; you ordered onion and now you're going to eat it. Open your mouth, dufus, or I'll open it for you. I said OPEN YOUR MOUTH.
