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.
Thank you! I was always morally opposed to ads. Glad to have another great reason to shun them
