In-and-Out Burger

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.
