Crush begins with visitors scrambling for cold cash

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 British financial authority is even recommending that tourists make sure to bring British pounds with them.

"I've had people asking me whether they should pay in British pounds or euros," said Alex Singer, a 27-year-old London cab driver. "I've also had Americans thinking that they can pay me in dollars."
