Janteloven is often used in Danish and Norwegian brooding about national character, but I don't think that a 81-year old literary concept is all that relevant for this discussion.
Your OP was AFAIU about a civil case in the US. Or are you planning a criminal case against the waiter and the hotel manager in the US?
I think that the migrant waiter was on a janteloven trip.
I am interested in the civil case for damages in the US, based on non-action of CarlsonRezidor's Radisson regarding the criminal behavior of its staff member.
