A
bill that is not
printed anymore and is hard to find, though there are still some in
circulation. Many
young people don't realize that there is such a thing as a two dollar bill, and using one (or more) to
purchase something with them as
cashier can be amusing, as they get very confused. (There are stories floating around about people using them and others
refusing to believe they are
real)
Apparently you can get them at many banks if you ask for them specifically.
