Ah reminds me of the time I tried to buy a Coke at the Denver International Airport with a Sacagawea. Of course the problem there was the cashier had no place to put it. The drawer didn't have room for a dollar coin. I did have a $2 bill also at the time. It would have been fun to try and pay with both and watch his head spin. Lucky for me, the manager there was bright and told him he could give it directly to him.
