It doesn't seem right to me that foreign countries can make their money any size, shape and color they choose with whatever figures they choose to honor on the obverse and reverse face of the various denominations.
Seems fairly obvious to me they are trying to trick Americans into handling the coins or paper money as if it were Monopoly money. For example, when I was in London they had a COIN that was just a hair larger then our five cent piece that was 10 pounds in value. At that time it was about 17-18 bucks.
So leaving that as a tip felt like being a cheapskate. Then I found out they don't even expect tips as it already included in the price. *******S!!!!
