How does a private security job as bodyguard for a celebrity compare and contrast with a security guard in a large and busy mall?

Well duh if your a bodyguard for a celebrity you'll get more money but if you work as a bodyguard in a busy mall you'll get dust.

A private security as it may seem most likely get paid a lot, because they are private. They have to protect the person that hired them, with like people throwing food at the people trying to hit them or that involves any danger to the person that hired them. A security guard is just like any regular safety guard, that makes sure there isn't any unwanted or illegal things happening. But they don't really protect anyone unless really necessary.
