@Jeffro - Seriously, you took that as a criticism of Jeff and Chris? Or of the book?

I was joking that this experience - of having to deal with fraudsters - will make them such experts that they could right their next book about dealing with credit card fraud. Admittedly, a pretty weak joke but I presumed it would be obvious, nonetheless, that it was a joke. Apologies to anyone who was offended.

Perhaps there is a cultural difference in our senses of humor. I'll try to be more American. (um ... that was also a joke).
