'Three cop cars pulled in and surrounded them': Cheap couple gets cops called on them for refusing to pay for a $9 salad bar

How much trouble is it worth going through to avoid paying for a couple of leaves of lettuce? Is it worth a run-in with the police that could possibly see you arrested and sent to prison, all because you didn't want to pay $9 for your salad after complaining about the toughness of your steak?

From there, you'll be forced to plan a daring means of escape. By day, you'll see yourself unwittingly participating in and then dismantling the operations of the corrupt warden running the prison while spending your nights chipping away at your prison cell wall, hiding the growing tunnel behind the poster of a beautiful actress—all because you couldn't be bothered paying for a couple of leaves of lettuce.

Let's be honest, the possibilities of this happening and becoming a reality aren't high—but I wouldn't say that they're zero either, as evidenced by this story in which this restaurant manager got back at some terrible customers by actually calling the police on them over their refusal to pay a disputed nine-dollar bill.
