I'm sometimes asked a question along the lines of the dinner example.
If I don't want either, I say "No".
Maybe I want fish. Or tacos. Or steak. But I want something other than the choices given.
Or maybe I say "Yes", because I want a hamburger pizza.
(which could be either a hamburger the size of a pizza, or a pizza with hamburger toppings)
..
Aaaannnd, now I'm hungry.
