When my cousins flew from HKG to PEN once about 15 years ago, they had just married HongKong men, and were going home to visit family. One of the flight attendants asked where they were from, and in conversation realised that they were all from the same home town - Penang, in Malaysia.
Then when the flight attendant found out that my cousins had both married Hong Kong men, she replied, "Good. You've caught some nice fat fish!"
Needless to say, my cousins were both flabbergasted.
But they laughed it off, seeing the culture one can get into when they live in HongKong!
