I would be a dishonest cheat? lmao you're the one that needs the class kid. I didn't go out and steal anything. If some delivers 700 dollars to me don't look for me to be running out the door after them.
That's where you're wrong.
It'd be more like, they are trying to give you $700, but they accidentally give you $1400.
If somebody gives me $700, I'd keep it.
If they were trying to give me $700, but they gave me $1400, I'd return the $700.
It's very different if somebody was trying to give you $700, and they succeed but they gave it to you just because.
