“Hey Coach Teddy, can you give me some money to go get some _____ or meet up with _____?”
”Sure, I’ll call an Uber.”
Teacher often buy school supplies for needy students. These supplies are not earmarked for certain individuals. If so, it is done above board and through official channels. And these supplies are directly needed for the curriculum. What were the Uber rides for? Where did these students go? What does it have to do with the team? You can see how this would raise questions.
Again, I’m not saying these were not done in good faith. But, and it seems like the school district agreed, there is a right way to do it and a wrong way. Adults unofficially funneling money or services to a minors is a great way to get in trouble.
