I was out buying a smoothie for lunch today. I gave the counter guy a 20 and he pulled out a 10 and change for me.
"Look at how crisp this bill is," he said, holding the nice, new 10. And then he crumpled it. Rather enthusiastically. "Sorry, I just had to crumple it," he said.
"OK," I said and took my change, slowly backing away.
I still drank the smoothie, though.
