I paid for my coffee and went outside to sit at a table.
Suddenly, confronted by the shop owner:
"HEY you paid with a fake bill! You can't use this!"
He came over to the table and angrily put the bill down in front of me, pointing,
"See here. And here!"
Oh. Yes. I do see. I had no idea that I had such a bill in my possession - it must have come from another transaction. Can you take my card? Can I write a check?
Shaking his head, mumbling, "Can you believe this? A pretty good forgery!"
To me: "Don't worry about it."
Laughing to himself, walking inside: "I'll take this over to the bank later."
RIP George Floyd
