Dead Pet Return Policy?

We were in Chinatown today, walking past a "pet store," when I had to stick my head in. We'd seen so many funky animals for sale, as food, that I was curious what qualified as a "pet" in this community.

I came upon the shopkeeper talking SO FREAKING LOUD to this very old woman. She was gesticulating at one of the glass cages, one full of baby chicks for sale for $2.50.

Apparently the older woman had purchased two chicks (not sure if these were meant to be snuggled with, or raised for eating?) and one of them was now dead(ish).

Loud Lady was explaining to Old Lady something about the wings being too cold. Or too hot? Something about how it was Old Lady's fault the bird was dead(ish) because she let it get too cold (hot?) But Old Lady kept saying that Other Bird was fine, and wanted to return Dead(ish) Bird. It was all creepy, though, and I was glad we weren't heading to lunch.
