The big question to keep in mind in these situations is: Did anyone die? Was anyone physically harmed or in danger due to the mistake? Sometimes we get so wrapped up in how important we are, that we forget what is really important in life. Geesh, make the guy buy donuts for everyone and call it good. If I were you, I'd make sure to give the guy some sort of card or token to show your support of him. Life is way too short. Inconvenience is one thing, death is another.
