AS bitter controversy rages over recreation centres for the legion of domestic workers, let's put a more harmonious light on the subject with a little quiz. Which household in Hong Kong employs the largest number of foreign maids? Step forward, please, the Harilelas, who have 34 Filipino maids at their vast Kowloon Tong mansion - all of whom, Bob Harilela tells us, ''are part of our extended family''. In fact the Harilelas, one of Hong Kong's wealthiest families, claim that they were the first in the territory to employ domestic helpers from the Philippines, starting in the early 1950s. Can anyone better that record?
