As bad as asking for a well done steak and iced water.
Slight thread drift, but what on earth is wrong with ordering well done steak? I'm a 'medium rare' man myself, but if you like your steak well done why shouldn't you order it that way? After all you are the one who is paying the (probably extortionate) price for the meal. If the chef is offended, hard luck, you are paying his wages after all. Afterwards you can celebrate by sipping your Courvoisier and Coke!
