Money / Gratuity
The dollar is the national currency of the USA. The dollar is divided into 100 cents. The symbol for the dollar is $ and ¢ for cents. The currency abbreviation is "USD". Unofficial names for the dollar are "greenback", "buck", "green" or "smacker".
1 ¢ (penny, bronze), 5 ¢ (nickel, copper), 10 ¢ (dime, silver), 25 ¢ (quarter, silver), 50 ¢ (half dollar, silver), $1 (a silver and a golden version; both are rare).
$1, $2 (rare), $5, $10, $20, $50, $100. There are also high value notes ($500 en $1000), but these are vary rare. All the currency notes have the same size and have the same black-green colour. So you have to be careful and pay special attention to the denomination.
Cash or charge?
When you are asked "cash or charge?" then you have the choice between cash or credit card payment. There is no need to have much cash with you (risk of loss or theft), you can almost always make a payment with a credit card.
Creditcard and Bankpas
In the U.S. America it is very common to use 'plastic money' instead of real money. In many cases a credit card is even required, e.g. hiring a car, motorcycle, RV or to book a hotel. Sometimes you are asked for an identification when making a credit card payment. When you are asked "Debit or credit?" this means payment by bank pas (debit card) or credit card.
There are ATM's (Automated Teller Machine) in the U.S. Here you can use your credit card or foreign bank card to withdraw money, if the card is equipped with the Cirrus and Maestro logos. Note that the fee for a credit card withdrawel is higher than that of a bank card.
In the United States and Canada it is customary to pay gratuities in addition to the tour fees. Some tour operators require a specific gratuity while others have a suggested amount. It varies with each tour company and will be provided upon request.
