95% of these types of misunderstandings are just down to lack of communication, usually in both directions. The customer didn't communicate what she was expecting and you didn't communicate what you were expecting in return, you both just assume you're on the same page. Getting annoyed doesn't help, just use it as school fees. It sounds like you're taking steps to avoid the situation repeating itself which is the best you can do after the fact.
