Ohforgodssake. Just give 'em the card and let the chips fall where they
may. CC companies (especially AMEX) are great about taking care of this
stuff pronto. That's why they make the big bucks, and part of what
they do for them. I've yet to find anyone who got 'stuck' for charges
in the end; just a bit of hassle, or not, in the immediate aftermath.
