I work in healthcare and we don't really care. We turn the other cheek and don't say anything. Of course, there's always that "one" that goes by the book and wants to throw her make believe power around. We don't like those people. vape until they tell you to stop and then start again at shift change. Plus, you can shut the door and put a sign that says "knock before entering" and then you'd have a heads up. Trust me...it works. Also, ask for extra linens (wash clothes, hand towels) and blow the vape into those. Them just tuck it under you when they come in. Yes, we have a no smoking policy at the hospital. People vape all the time.
