15. Wanna Be Gangsta
Not like actual gangs, but crew members get pretty cliquey. It’s normal human behavior most of us forget after we graduate school. Put people in forced social situations, like jail or school, and they form teams. They may divide into cultural lines or jobs, but here’s a crazy fact about these cliques: on at least on one cruise ship, they called the cliques mafias. On that ship, it was the Filipino mafia who could score after hours booze for a price. Maybe crews are gangstas.
