"Customers and our team have the right to go about their shop or work safely and without threat."

The challenge has appeared on popular social media app TikTok and has resulted in at least one large supermarket fire in the US already.
The WestCity mall fire temporarily closed the store and resulted in dozens of firefighters being called to battle the fire at the Countdown there.
