I used to keep aquariums. One day I was at a pet store buying fish on a cold winter day. As the check out woman was looking at a couple bags I had with fish in them, this exchange happened:
Clerk: "Did you bring any towels to wrap these with?"
Me: "No, I didn't."
Clerk: "Oh, they should be ok. Plastic generates heat."
Me: "Excuse me?"
Clerk: "Yeah. Like sometimes when I'm getting my hair done they wrap plastic around my head and it gets really warm."
Me: "..."
