The “Excited Expat” has never had a passport, never left their hometown, never attempted to speak a second language
and had little or no exposure to different cultures. The probably have never eat Chinese or if they had they think Lemon Chicken is a regular Chinese dish.
Excited Expats have no extra luggage (ie wife, kids, animals) and therefore their drain on the company is less than the “Xtra expat” who has an entourage. They also tend to have no expectations and arrive to find the city of Hong Kong expensive, overcrowded and exciting!
Hang out in the Wanchai Bar district you will find one of these expats there. Eventually they move out of this phase – because I suspect that this is purely a phase not a permanent breed. See them as a puppy, over zealous, eager to please, into new stuff and clearly missing the point at times.
