This is a surprise? This is more or less the case everywhere. Maybe not as wide open and acknowledged as at Oregon, simply because it's such a part of the culture there, but it's common.

I know a guy who failed a test under Wacker and one under Mason and it was just a "wink wink - don't do it again now..."
