In this video, you see the guy behind the wheel of a Jeep get out of his car as he's yelling "go back to China," and calling the person recording him a "stupid g**k."

According to witnesses, this all started Sunday inside Sephora in Irvine, CA ... and the couple in the video allegedly refused to wear masks, which upset nearby customers ... including the woman recording this video.

They met again in the parking lot just outside the store ... and on top of hurling epithets, the guy charged toward the woman in a threatening way, saying ... "Are you really that stupid? You know that recording doesn't do anything."

Doesn't look like police got involved this time, and the guy threw one more bigoted parting shot as he pulled away -- "Stay home, and thanks for giving my country COVID."

Kudos to the woman who got the brunt of this hate speech -- she's choosing to focus on positives, and posted ... "I understand there's always unfortunate people living in hate. It's pathetic."
