<human>: Ok, so this didn't happen today, but whatever.
I was walking down the street when I saw a homeless guy and since I was in a good mood I decided to give him a dollar. I didn't have much cash in my wallet, but I thought I could feel some in my pocket. I stopped, turned to him, reached into my pocket and pulled out what I believed was a crumpled dollar bill.
It was a receipt. For a $4 organic chai tea latte, which somehow makes it worse. And I was standing there for probably a solid ten seconds with my hand out trying to give this guy a receipt while he just stares at me.
Finally after a painfully awkward staredown I realized why he wasn't taking it, but it was too late to just move on as if nothing had happened, so I said the only thing I could think of: "can I pet your dog"?
He said no but the dog was already licking me so I just started petting it anyway. Then he said "whiskey" and I was like "what?" and he said "the dog's name is whiskey" and I just said "ok" and walked away.

Can you condense the text into a few key points?
