食骨 means you have to buy something that you didn't ask for (e.g. jewellery), or watches that will most likely lose money in the secondary market, as a bundle to buy a Rolex watch. I hope this makes sense.
@@KCTimeShareHK Got it. it is like bundle with some non sense stuff. Like buying a new car, you have to get the carpet, emergency kits, special polished wax...etc. Thanks for the explanation 👍 and video. BTW, I was told if you try to get a Rolex from authorize dealer in Hong Kong. The popular model like submariner, GMT. they are mostly out of stock. Is this correct?
