Woman Refuses to Wear Mask in Store, Fights Manager with "Martial Arts"

Warning: Video Contains NSFW Language

Here's what the person who recorded the video says:

I was at a Shoppers Drug Mart when all of a sudden a woman was walking around the store without a mask. The manager and staff told her she needed to wear a mask in order to walk around and continue shopping, this made the woman erupt in anger and she decided to make racist remarks that the manager knows martial arts because she's Asian and started to attack the manager. The manager was polite and didn't start anything and was attacked without notice. She made remarks threatening her with her own blood. Security came to the scene shortly after.
