I take most stories like this with a grain of salt. I've been to Riverfront many times and always had a good experience there, so I found the story to be unsettling at the least. The e-mail I received also had the KTN's e-mail address on it, so I'm wondering if that was just to try to add credibility to the story.
If its true, then maybe this lady will step forward and own up to her side of it.
