>If I were still a high school kid, I hope I would be wise enough not to vibe-code an app that handles money. Because any time your app handles money, all kinds of laws and regulations may end up applying to you. How do you handle refunds? How do you handle claims (true or not) of fraud? How do you handle actual fraud? If your app has a bug that means someone's payment didn't get sent to the city / parking lot owner correctly, and the customer's car gets towed, you're going to have an angry customer calling you and demanding that you reimburse their towing fees, or threatening to sue you for negligence, or something.

The difference between a highschool kid and an adult is that the highschool kid thinks you need to handle all that and the adult knows that having all the exception paths be broken and require a call to a customer support rep that can't actually fix the problem is actually a revenue increasing feature, not a bug.
