A buyer recorded the incident inside the store on Friday.
The woman in the video was angry after being questioned about why she was not wearing a mask.
Los Angeles residents are required to wear face covers when they are in public stores and inside other companies to help stop the spread of COVID-19.
Other buyers reacted to the video.
“I feel kind of bad because people are embarrassed and they have a medical condition, so they can’t wear a mask. On the other hand, we now know that the mask is helping to stop the spread, so we should, especially when we are in lines and places, we must be more aware, “said buyer Sigrid Matthews.
“I think you should still wear a mask just for the safety of others, especially for the elderly and children,” said shopper Jessica Govea.
KABC-TV contacted Trader Joe’s to comment on the incident, but did not receive an immediate response.
