I broke a drone and then returned it.
I'm curious as to why you returned the drone?
This is the first time I dealt with a broken drone and I thought that was the right thing to do.
Unfortunately, it's not the right thing to do.  Assuming it wasn't broken when you got it, you broke the item yourself which means it'so longer available to be returned.  If you returned it anyways you took advantage of someone!
I knew that but I wanted to see how much PP I could get from them so I took it back and I got it for free.
You shouldn't be doing things like that, as it is technically a type of theft. Is that the type of person that you want to be? Someone who commits crimes?
