Is there any controversy about a piece of cake in the first National Lawyers Debate Competition?

It is a crime of extortion. According to the definition of criminal law, this case is a typical customer who bought a cake and blackmailed the shopkeeper with a red plastic rope in the cake for 250 thousand yuan. Meet all the requirements of the crime of extortion.

Attached to the definition of the crime of extortion: for the purpose of illegal possession, it refers to the act of extorting public or private property by threatening or coercing the victim for the purpose of illegal possession.

But I think he can be raised as a topic of debate, because the case itself is the fault of the shopkeeper, and it seems that the customer is the just party.
