These guys have an Internet dispute.
The Max Headroom of How to be a Billionaire send a German Legal Letter to another Crew using his Bodyguard ringing the door. The other Crew feels threatend.
We do have to understand that both Crews are families with kids. That all of that happend in Cyprus. That German highly decorated Bodyguards look like older Rockers post a failed Bodybuilding career struggling hard with the Mediterranean climate and ... That Cyprus is an independent nation.
The last statement is the important one. All parties involved, potentially also the Maid, are Germans acting based on German law... in fucking Cypress. Cypress is both part of the Commonwealth and has a School of Law heavily based on the English Law of Commons.
So, he actually would have needed either a Cypriot Law Firm, an International Law Firm specialised in Commonwealth Law that files a legal case against the other party, because outside of Germany no Lawyer can fine shit without a Judge say fuck.
