I agree, cash is fun in Germany. I think it really helps that the 1 and 2 euro coins are available and used in circulation. It was so nice going into the Späti and buying a beer with a single coin.
Change feels unnecessary in the States since the highest denomination that’s widely circulated is the quarter dollar. There are dollar coins, but they are hardly ever used.
