Ya I work in healthcare and do none of these. “Good morning Mr Smith” in a loud tone wakes up 80% of people. Good morning with a shake of the shoulder wakes up 99% of people. That last 1% is the ones you worry about. 

Anyone using a sternal rub to wake up a healthy, non-sedated patient is idiotic.

I thought a sternum rub was only ever used to see if a patient was unconscious. As in, not sleeping, but in some sort of medical distress.
