Who is Jangbu Panasa from Princess in Pink and what is their importance?

Jangbu Panasa is the busboy at Les Hautes Manger. He is fired after he trips on Rommel and spills lobster bisque all over Grandmere. Lilly begins a protest against Jangbu's unfair dismissal, and she also breaks up with her boyfriend, Boris, and begins dating Jangbu. Ultimately, Jangbu sells his life story to the tabloids and returns to Nepal with enough money to be wealthy for the rest of his life.
