So what really happened here? A teacher took an all-male group of students to a restaurant where the waitresses wear a little less clothes than in other places. What is the big deal? - I'm sure male high school students already knows how big-busted women looks.
What also puzzles me is that the school bends over backwards to appease the parents of the single student. Even if there was a reason to believe the teacher did something wrong, surely a milder sanction would be in place.
I would be happy if someone could clarify exactly why some people are so afraid of anything remotely sexual and why the rest of American society seems so afraid of these people and so willing to appease them.
