@JaneAir - You're probably right.
One thing about contracts most people don't realize is if a contract isn't legal, it's not enforceable. So if you get swindled into signing an unlawful contract, don't let the person who got you to sign it push you around. If a contract isn't lawful, a court won't enforce it.
The same thing goes for waivers-even if you sign a waiver you may still be able to recover damages. A lot of times half the purpose of a waiver is to make the person think they can't sue. But sometimes you can!
