If you had a friend who is a surgeon, pilot, or school bus driver, and you are pretty sure he is an alcoholic, would you tell?

Or, any other profession or hobby that really requires you are not inebriated, would you call the company and tip them off to test that person?

Let’s say your child rides that bus, or your spouse sometimes flies on the route, so it’s not only regarding other people, but your family specifically, then do you tell?
