why are you fighting about it when it isn't your money or contest? Be grateful he decided to give something away at all. He isn't obligated to spend any money on anyone.
If you feel so strongly, set up your own contest with your rules, and give a prize as you see fit.
If Bun decides to not give the prize he doesn't have to. He made the contest and is using his money.
this whole "it's not fair" thing is really, really shocking me
