A patient walks into an optometrist's office for an eye exam. He walks out an hour later with a box of contact lenses, conveniently purchased in-office with the eye-care provider's encouragement.
If the patient is typical, he probably doesn't stop to wonder why he wasn't provided a copy of his prescription. In fact, he's likely wholly ignorant of the significantly cheaper lens options available online. And he's almost certainly oblivious to the fact that his friendly optometrist just violated the law.
