I live neither a sheltered life nor am I an inmate. I wasn't aware that seeing someone use a two-dollar bill to pay for something was a criteria for civilization. I have also not seen anyone use a Susan B. Anthony Dollar coin in years and have not seen many of the new dollar coins used as well. I don't frequent race tracks, casinos, gambling establishments, or wherever people use two dollar bills in abundance.
If the fact that I don't see two dollar bills used in a purchase transaction bothers anyone, I suggest that person get over it. Surely, you have a lot more important things to worry about; such as, getting your thumbs out of your backsides.
