No, they don't guide you to the exit, they guide you past the collection.

The whole point is that the thing is set up like a very long serpentine track so that you 'see everything' rather than that you can go to the one thing you want and then to the cash register. This is because they - rightly - figure that if they can keep you in the store longer and expose you to more stuff you might buy more.

You can enter the warehouse directly through the register area. No one is stopping you.
