Only partly off topic. One or two others got it, but I'm sure they know it. I prefer using language a bit softer than "Refused," because it is less threatening to the other party. In this situation, I'd try to smile and use the word "Decline." Over many years, now long past, I declined three times. One for a major Mx issue and two for weather related problems. While the employer/client does carry some weight, our butts are always on the airplane and reservation of said part has always been very important to me. Try to be polite, but do not compromise your professional standards.
