Yeah, I fall in the category of a Christian who is uncomfortable with any forced participation in faith, be it on money or in the Pledge of Allegiance. I'd likely have just quietly backed away, but if he caught me in the right mood, I might have engaged him in a fierce, "Do you really think a believer in God should be spending time getting God's name on money or could there maybe be something more appropriate to do with that kind of time and clout?"
