I have to admit, this is one of the few occassions where having a foreign name actually offers some advantage in this country (US).
My wife prefers not to make this kind of calls at work and is too busy at home to be bothered (she does love the miles accumulated). All I have to put up with is to be called "Mr. my wife's last name".
What a heck. I will trade that for tens of thousands of miles each time EVERYDAY!
