A nationwide technical outage has caused chaos at Woolworths stores.
Registers were shut down on Monday afternoon with stores unable to make sales.
Customers shopping at Docklands in Melbourne, and Marrickville, Bankstown and Cowra in NSW took to the supermarket’s Facebook page to complain they couldn’t pay for their groceries.
One user, shopping in Sydney's north, wrote he was trying to buy his family dinner at the Crows Nest Woolworths but told he had to "leave the store immediately".
Another wrote they were buying groceries with their two children in Brisbane when the glitch began affecting the store's systems.
"Shopping with two young children is bad enough then I get to the checkout and your IT system is down and I can’t get any food," they wrote.
"An hour of my day wasted."
One user posted a photo of the Bankstown store with its doors shut.
An annoyed shopper in Adelaide told 7 News he "can't believe it" .
"They're not serving anybody, people are queuing up all around the place," he said.
"And the whole shop has closed down."
