To be honest i liked when it started but its becoming a chore, last time he started just complaining for 10 minutes about how he didnt know how to tip a waitress extra for information because he is from space and in real life he didnt had any idea and that waving virtual money isnt the same as real money etc. Like you said i should just kick him out or TPK the game or just gonna kill his brother in the most meh way possible like "you walking and on the other side of the street you see your brother, he cross the street and then he is hit by a bus"
That does sound irritating, not just for you, but for others in the group. Does this person play lots of emo vampires? It sounds like the type.

I wouldn't kill his brother, since that is the biggest tether you have on him, and you are saying you want a tether. If you want Johnsons to be able to intimidate him, destroy everything around him, bit by bit, most especially his contacts. Nor would I kill the player, or even injure him directly. (Just remove him from the game if you want to go that route) Have his brother or a contact, or one of his team's contacts, beat up or maimed. (Or one of that person's relatives) If he's indifferent to this, have people stop talking to him and avoiding him.
You can also do things like have his car or apartment explode. (with him near it, but not in it) Once again the more this type of thing goes on, the more he becomes a pariah, and people avoid him as they don't want to draw the powerful Johnson's ire.
The above is an extreme tactic, but it's kind of sounding like that is what you are looking for. It might be best to talk with this player and perhaps with the other players. I know many players get upset at a showboat stealing all the GM's attention and the game time, which is what he's doing with the waitress thing.
Also, reward players who are actually doing things constructive to the campaign with spotlight time. And vice versa. Don't indulge someone who wants to waste everyone's time. The lack of spotlight might motivate him to do something constructive.
