That uncle, his name is Chua. So I usually address him by Uncle Chua (:
well, guys, don't be scared by his thick moustache and fierce voice man. He's actually a very nice guy! dealt with him in many ways and 90% of the time we ended up talking nonsense before I realised I am late for work! :X Another thing about him is that he is very knowledgeable! He knows alot and won't mind sharing his experience with anyone. I remembered him telling me about blotchy anthias, his farms in Indonesia and his diving trips around the islands in Indonesia. So for a newb like me, having someone as such to unrequitedly share his life experience with me is a honour.
So, really, let's not get frightened by his voice or look. He's really not that scary. To break his ice, just go in and say "HELLO UNCLE CHUA!" and volia, one good day of cheonging in the wake at RB!
Happy Reefing,
