A bit late

One of my correspondents had an out-patient appointment at his local hospital the other day – a follow-up to some treatment. “All okay,” the technician who had done the testing told him. “See you later,” the tech added as he headed back to his lab.
    It wasn’t until he was on his way home that my correspondent realized that “See you later!” is the last thing you want to hear from someone who works in a hospital.
