Never ask "how much?" Ask "whats the donation to spend time with you?". No vulgar language. Also if you have a specific question. Tell them " I have a question to ask you, if your comfortable answering". You can always ask them anything when you see them face to face

Also be prepared for a no if u ask face to face. Its always the safest route. And what u may be interested in might be an extra tip so be prepared for that too. If its an absolute deal breaker that u need that service. U are bettwr off using redbook. Abreviations or terms after asking her for permission.

Basically, talk as if you are being recorded by a judge. Because she thinks she is.
