If you return the rudeness, then the interviewer will most likely tell everyone else in the office and other people in the industry how rude you were. They will obviously not admit they were rude first. The best you can do is to answer all the questions to the best of your ability and keep a smile on your face.
You want to be careful about outright leaving in the middle of the interview. Unless the hiring manager is downright abusive, it is best to stick it out. In the event you receive a job offer, you should weigh all the information you have carefully. If the interviewer made a bad first impression, then this may not be the right company for you. There is plenty of work out there, so you should feel free to politely decline the offer.
