Tales of people who doesn't worth it (I don't understand your intended meaning): The robber

I will point my gun against at the cashier. Then I am going to yell: “Put all the money in my bag. Right now! And won’t don't call the police or I’m going to shot you.” The cashier is going to be frightened and is going to obey my order. It is easy to rob a bank. The best of all part is that all that I need is a toy gun.
