Joe: (walking into McDonalds) Hi, I'd like a Big Mac.
Cashier: Okay, here's your Big Mac and here's your Coke. That'll be $3.99.
Joe: Uh, I don't want a Coke.
Cashier: Sorry, they're bundled.
Joe: What? I'm not paying for a Coke!
Cashier: You don't; the Coke is free.
Joe: But wasn't a Big Mac $2.49 last week?
Cashier: Sure, but this latest Big Mac is far more innovative. It's got integrated Coke!
Joe: I already bought a Snapple across the street... I'm not going to drink the Coke.
Cashier: Then you can't have the burger.
Joe: Okay, fine, I will pay the $3.99 and throw the Coke away.
Cashier: Oh, you can't do that. They're seamlessly integrated. Inseparable.
Totally Joe: How can that be? They're two totally separate things!
Cashier: No, watch. (takes Big Mac, dunks it in a tank of Coke)
Joe: Why did you just do that?!
Cashier: It's a benefit to the consumer. Otherwise you'd end up with two different, inconsistent tastes. This way you're assured of a continuous taste across all your foods.
