I would give her the benefit of the doubt. Its alot to deal with all on the first day. She may be trying to scam you but I would just restate nicely the contract and offer to answer any questions she might have. Like saying something like "I know in the first few days it all gets confusing. In my contract it states (whatever your contract states). If there are any other questions I would be happy to answer them for you"
Then maybe you can feel out if she is trying to scam you or if she's just an airhead (like me) LOL
