100s of Supermarkets, Britain: Across the length and breadth of Britain, thousands of shoppers were unable to buy food today in what could be a sign of things to come.
Investigations are ongoing, with Store Manager realising it was causing "great inconvenience" to customers. Dozens of shoppers reported the problem on Twitter, the micro-blogging social network site, with several complaining that they had been unable to pay for their shopping.
One twitter user said: "Massive computer glitch whilst shopping today. All the card machines stopped working, and then the ATM went down!"
Another user said: "Saturday afternoon in the Supermarket. All card payments down. Chaos!"
Others reported scenes of "bedlam" as customers attempted to withdraw cash from ATM machines so they could pay for their shopping.
One shopper tweeted: "Payments glitch hits the Supermarkets. A return to the dark ages as Sainsbury's are only able to take cash."
Another Tweeter added: "Computer glitch preventing card transactions at every single Supermarket in the UK. Chaos would be an understatement."
When the food riots come, to signal the end of time, this will be how it commences, when a computer virus brings down the entire banking network.
