Halitosis

Are these people that oblivious to their rotten breath?
Four times this week I have had to deal with customers who must have eaten dog shit on the way to work. In each case I had to have conversations with these people lasting 10 minutes or more. I understand garlic breath after an executive lunch, I even get cigarette breath, but for crying out loud, BRUSH YOUR FANGS!!!!!!! Eat a mint do something. My next and only option is to projectile vomit on them to make them smell better.
