The first one rings a bell and reminded me of a restaurant we went into. A young gal gave us each a menu. I noticed Bison Burger on the menu. When the waitress came back I said I would like the buffalo burger. She looked at me like I was an idiot and said, "We don't have anything like that."
I pointed to the Bison Burger and said, "What's that then?."
She laughed lightly like I had just made a joke and said, "Silly! That's not a buffalo burger, it's a Bison burger."
I saw no reason to try and educate her.
