1. {calls at the start if appointment time} "I'm going to be 15 minutes late"
  2. Patient comes 30 minutes early, and right as you come to seat them asks to use the restroom.
  3. "Sorry, but I didn't brush before coming here"
    This is one of the most difficult. It makes the cleaning so much harder and more disgusting.
  4. You can't lie my chair back.
    I'm sorry, do you sleep sitting up?
  5. We know when you're lying.
    I don't actually hate this. It's really pretty hilarious.
