Sorry, I don't believe the part about the lawsuits. Replace that with threat of violence against the principal by kid's dad, and you've got a good story.
OTOH, even a really stupid admin wouldn't have been THAT stupid back in the day, so maybe it doesn't matter...
Here's a story from "back in the day"
Scenario: Decades ago, 8th grade, Catholic grammar school in Chicago, a few weeks before graduation. I was 13.
The lay teachers (no nuns taught 8th grade) would frequently pick a boy to go to a nearby restaurant and make a take-out "lunch run" for the faculty - give the kid some money and an order, and he would dutifully bring back the food and any change . . . and then go back to his classroom for his cold sandwich.
One day it was my turn . . . so I did as I was told, and upon my return met the teacher in the hallway and handed over the teachers' order and the (correct) change. Teacher then asks "What's in THAT bag?" Told him "I used my own money to buy myself a burger and fries."
"DID I TELL YOU YOU COULD DO THAT?"
"I don't need your permission to spend my own money!"
"Well, you can't do that, it's unfair to the other students, so hand it over."
"No!"
"Hank, I said hand it over - NOW!"
"You may get away with stealing pencils, combs, and erasers (different story) but you are NOT stealing my food!"
With that, I turned away from him and headed back to the classroom, with the teacher calling after me to get back there. I ignored his calls and went back to the room - I wanted witnesses. I was fully expecting his hand to fall on my shoulder - at which point I was going to whirl and punch him in the nose just as hard as I could. I was big for my age - he was bigger - so I had no illusions about winning a fight, but I knew I'd get one good punch in.
He
didn't follow, or lay a hand on me. I think he realized that if he did, the situation would balloon out of his control, and HE would be out of a job for sending a kid off-campus during the school day.
And . . . I'm
quite sure he didn't want to deal with my Dad.
