We had no problems using American credit cards in Edinburgh, Scotland, at any establishments or businesses in August ’07. These included restaurants, museums, theater box offices, retail establishments and grocery stores.
A real plus at the restaurants — almost without exception, when I went to charge a meal the server came to our table with a handheld device in which my card was swiped.
If the establishment did not automatically include the 10% service charge, which is apparently standard operating practice in the U.K., the screen on which I signed and accepted the charge permitted the addition of a gratuity.
