Mark Few refused officers' orders repeatedly and appeared very annoyed and frustrated with cops during his DUI arrest in September, new police video obtained by TMZ Sports shows.

The Gonzaga men's basketball head coach was pulled over in Idaho at around 8 PM on Sept. 6 ... after authorities said he was swerving in his car and driving erratically.

And, in footage of the stop, you can see Few wasn't happy about any of it.

Few -- who told cops he was on his way home to Spokane from his vacation house -- initially refused to get out of his car when cops ordered him to ... and he then continuously stuffed his hands in his pockets despite officers telling him to keep them away from his shorts.

Later during the stop, Few refused to do any field sobriety tests -- claiming they were "totally subjective," and adding that previous injuries wouldn't allow him to do the tests properly.
