Manitoba Public Insurance

This white guy who gave me my driving test was unfair not polite at all, he said I didnt stop at stop signs long enough that I didnt do my shoulder check at my parallel parking test, he was not even watching me, and I did do my shoulder checks because ive taken driving tests and know the importance of it, I did stop at stop signs and there was no vehicles, I dont know what he meant by not stopping long enough was I supposed to wait an hour? very unfair, roadtests should be videotaped for proof.
