He clearly has an inferiority complex and needs to feel important. Personal chef is wife of a Brooks employee that probably does batch cooking, not there every meal asking "Hey Josh, what do you want for lunch?".
Then he must have a nutritionist, who will have lots of other clients.
Obviously, an agent, also with other client.
A sports shrimp, with other clients.
Media person.....
He is so full of himself that wants to appear important. You can tell by his clothes and style. He needs to attract attention and he tries to do by boasting, dressing up, and trying to mess with other people.
He makes me laugh with his physiological war with Jakob.
Jakob, on the other hand, attracts attention by being himself. He is authentic. Josh is a clown.
