- I want buy something worth $5

- I get produkt, but no change for balance of $15
- Shopkeeper no understand why I angry because he not give me balance of money owe to me. Shopkeeper say $15 is large tip.

In real world, this called stealing and is crime.

It Bitcoin world this OK ?

It's not OK, it is stealing and it is a crime, but since we have no cops, the best we can do is give bulanula a big sign saying "SCAMMER" which he has to wear for the rest of his life* as a warning to others.

*He actually only has to wear it until he gives the money back and then he can put this all behind him, but he's made it clear that he's not going to do that because he's just that much of an asshat.
