FILE - A VISA credit card sign is posted with other credit card companies at an ATM bank machine in San Jose, Calif., Sunday, March 16, 2008. Tourists be warned: The Olympics crush has begun in London _ and so has the scramble for cold, hard cash in the pricey British capital. Lines are getting longer at ATMs, visitors are in sticker shock over British prices and some befuddled tourists are wondering what currency to use. Stores in the Olympic Park only accept certain credit cards and a top British financial authority is even recommending that tourists make sure to bring British pounds with them before they land.
