What?! How is anyone defending his behavior?! Kthnx, sorry, but there's a way of getting through to people. What he was doing was dramatic, over the line, and just downright creepy! It's not one or two things, because I could see him saying "Well, if ya'll eat donuts, fine, but not in the breakroom." sort of thing.. but EVERYTHING combined make him a total retard!
If he promotes health, fine. But promote it, don't insult adults while you're at it. It's just not professional.
