Ever notice on cruise ships? A real lot of staff is Phillipino. Some have speculated their size is a plus for providing for the crew’s needs.
I think the Philipino cruise ship crew popularity is cultural, in that it is both an admired pursuit for Dad (or Mom) to go off to sea, and send back some good money to support the family. Plus, they tend to be very personable and hospitable, making them valued service employees. Also, musical talent is fostered, and many of the musicians are Philipino.
