Maybe. I know if I was sitting in a room where the manager did this I'd be embarrassed. As another poster pointed out, an interviewee can usually profit from sticking out the interview, maybe learn something (even if it's learning what people don't know). At the least it's practice at suffering fools. Same from the other side of the table. Most people don't know how to interview candidates; you all know this, because you've all sat through clueless interviews. But those people (you, if you've ever interviewed a candidate) are usually competent and nice people, they just don't have that particular skill or experience. So follow through, do the whole interview, because you need the practice. You've brought an expensive learning resource into the office, so learn from him. Finally, there's nothing wrong with being gracious and leaving the candidate with a positive view of your company and of you. Maybe he'll treat the experience like "dang, I've got some stuff to learn," rather than "those dudes are poopy heads." In any case it's as good for you to be gracious as it is for the candidate.
