She then "opened her car window and screamed abuse at people for wearing masks as she drove off" according to the other customer, who wished to remain anonymous.
The "aggressive" anti-mask rant was slammed by her follow shoppers, who say workers are doing all their can to continue to protect the public.
The person who filmed the rant said: "I had just paid for my items and was about to walk out when I heard shouting.
"I turned around and the woman was shouting at the lady behind the till, saying 'this needs to stop, wearing masks doesn't work - it's ridiculous. - you are all idiots.'
"The woman behind the till was so shocked and said she was just following the rules before asking her to leave.
"The customer carried on screaming and waving her arms around aggressively and started calling the staff paedophiles and idiots because they wore masks."
The witness said the woman continued her rant even after getting into her car outside the branch.
The person added: "She went to the car park with her shopping and was still shouting, she then drove away, but opened her car window and screamed abuse at people for wearing masks as she drove off."
