A kind drunk boy becomes enamored of my glasses and comes to find me after buying some chips, waiting for the F train. He holds out the open bag for me, and I politely decline. His friends come up behind him as I also politely decline to exchange contact information so he can take me to a "punk or metal show".

His friends: "Dude, are you offering chips to strangers!? We don't know this guy."
me: "He did, and it was very sweet of him."
friends: "and why didn't you get salt and vinegar!?"
him: "Because fuck you, that's why."
