Well no parks/chains take it as seriously as Disney in my opinion, but you're right, I think they should.
I do know that CGA does take line jumping pretty serious, when people are caught anyway.
But the thing is that they never are. Whenever I go, and go to CGA quite often, people line jump and no one does a single thing about it, even some staff have seen it and not said a word. Maybe it depends who is monitoring the line because some of the employees don't even care.
