I'm going to make a kid who cut me off pay for my coffees
Why would you make them do that?
I want them to understand the consequences of their actions.
It's understandable to be upset about someone cutting you off, but its unwise to ask them to pay for your items if they do. It may end up turning into a bigger issue than it originally was.
My feelings shouldn't matter when it comes to the law.
I think that your feelings are getting too involved. You should not make someone else pay for your things.
