Addendum.

I forgot -

For the 2nd half of the exercise, I switched the scenario around, and said to envision an expensive restaurant downtown where the 1% eat food that's flown in from all over the world and served up by minimum-wage workers.

"So imagine there's this obese girl," I began, "And there's some crocodile meat that's flown in from Africa..."

Later, I said that the construction "the must-be-eaten crocodile" would imply something like that it was so tasty that the girl had to eat it, or perhaps the waitstaff disliked the obese girl because she was obnoxious, and so they made sure she ate it because they could mark up her bill 5000% in revenge.

"She sounds a lot like Kim Kardashian," my tutoree was like.
