A software glitch over the euro caused the temporary closure of a Superquinn store in Dublin last week. In preparation for the currency changeover in January, the tills converted the prices into euros ­ but they then charged this total figure in Irish punts. Shoppers with a basket of groceries that should have cost I£20 got a shock when presented with bills for I£25.39. As soon as the error was discovered, customers were given immediate refunds and the store shut down briefly while IT experts sorted out the problem. "It was a baptism of fire," said one of the staff at the city suburban store. He added: "However, the customers accepted it was just a teething problem with the new system, and everything is working fine now." None of Superquinn's other 18 stores has been affected by the problem. {{NEWS }}
