The moment a Canadian woman berates grocery clerks and tells them to 'go back to China' for not understanding English has been caught on video.

The video, shot in a Toronto Foodymart on last Friday evening, shows a woman in a motorized wheelchair breaking into a rage over communications difficulties with the Chinese staffers.

'The lady went up to the counter and asked if anyone knew how to speak English. She didn't even ask for food at the beginning. I think she was looking for trouble,' Frank Hong, who shot the video, told DailyMail.com.

'The lady went on a racist tirade screaming about how they needed to know English and screamed “Go back to China” at least a dozen times,' Hong said.
