Nick, no offence, but that's a poor analogy as at least the service of food is part of the waiter's remit as they work in the food and drink industry. The whole point of this story is that the nurse doesn't work in the spiritual welfare industry, she's employed as a medical practitioner.

Also, the crux of the matter in your analogy is whether the waiter had proffered the recommendation or the customer had asked for a recommendation. Too very different things.
