Fearing that a new way of charging customers by credit card could give shoppers the impression they are being massively cheated, supermarket owners yesterday called on Greek banks to change the system that is due to come into operation with the introduction of the euro. Banks have said that as of January 1 – when the new currency comes into circulation – shoppers paying by credit card will get receipts that bear no decimal point. But in a statement yesterday, the supermarket owners’ association (SESME) said this could lead to great confusion. According to bank instructions, a 50-euro purchase should appear as 5000 on the receipt. But this might mislead consumers into believing they had been charged 5,000 euros, SESME said. The spokesman said that Simitis maintains regular correspondence with IOC coordination commission chairman Denis Oswald, in what appeared to be a further hint to Angelopoulos-Daskalaki that the government wants to keep the Games under close scrutiny. Venizelos told the meeting that five Olympic projects being undertaken by the organizing committee must be subjected to regular scrutiny and called for tabs to be kept on its spending, sources said.
