Or a European, or someone from any of the vast number of places where people can buy lunch with the change in their pockets. We Americans are used to thinking of coins as nearly worthless objects that accumulate around the house, needed only when we're buying a drink from a vending machine, paying for a parking space, or trying to avoid getting more coins in change. Every once in a while the government tries to get us to use dollar coins, but it never catches on, mainly because the old familiar dollar bill continues to exist.
Anyway, today I used $20 bill to buy a book of stamps from the vending machine at the post office, so I got 13 Sacagawea dollars. Now I have spendable change, even if I may get funny looks for it.
