Bren, I think it's different in office settings than it is for us in the field.

For one, client controls whether or not you're in her house.
If you say something inappropriate she can ask you to leave or at the very least not schedule next visit.

Beyond that, unless you get picked up by the cops while at an appointment, chances are you're fine.
Seriously, if you were that inappropriate, why didn't she call the cops on you? If there is no allegations of restraint, kidnapping or rape, you're fine.

I've been thru all sorts of training in corporate world as it relates to inappropriate behavior and sexual harassment.
My personal opinion is that in a lot of cases is an opportunistic crime, meaning if someone didn't get the promo they wanted or pay raise they feel like they deserve, calling wolf is a way to try to force the hand.
